Additional information

1 - The HD Op4 v_crossbow_reference.bmp is 256x256 while HD HL1/Blue Shift are 296x255. The left area of the HD HL1/Blue Shift textures are only repeated after the right area. The HD Op4 texture has been used since it's power of 2.

2 - The LD Op4 model has the right arm while the other LD variants don't. It has been removed.

3 - All HD variants have the right arm. They have been removed.

4 - All HD variants sequence idle2 are motionless. It might have been intended to be this way but I replaced the sequence with idle1 sequence and moved the string in unloaded position. FPS was made 3x faster so it has the same duration as in the original LD animation.

5 - All HD variants fidget2 sequences appear to be identical to sequence fire3. Because idle1 has the same number of frames and fps as the original LD, it is currently used as a base for fidget2 until a proper sequence is made. See #20 .

6 - All HD variants draw2 and holster2 sequences have the string in loaded position while it should be unloaded. They also have clip bolts which should not be here. This has been fixed.

7 - The clip bolts are visible in HD fire3 sequence. They should not be here since this is the fire on empty sequence. This has been fixed.

8 - The original LD HEV hand back has no faces. This is noticeable in sequence fidget2 - frame 34. The LD Python hand reference has been used as a base.

9 - The new models have been tested in game. No issue has been found.

Add the following Otis sequences:

• fence (otis_fence)
• wave (otis_wave)
• dead_sitting
• cowering
• range_fire (otis_range_fire)
• otis_dumped
• otis_dumped_idle

Additional information

1 - For otis_range_fire, the following changes are made:

• Use barney/ba_attack2.wav instead of weapons/de_shot1.wav
• 5001 replaced by 1003 (likely used to fire event)
• Renamed otis_miss to barn_miss so they can fire different triggers

2 - HD Barney shoot_gun sequence fingers pose have been applied to otis_range_fire so the hand fingers are rotated.

3 - LD Barney had duplicate gun holster polygons in Gun-Hlstr mesh. It was removed.

4 - BARNEY-X_Template_Biped(Gun)1 has a different hand mesh than the ones used when holstered. It appeared on top of the default hand mesh.

I decided to keep the default mesh and adjusted the gun position. Having the same hand meshes across all 3 submodels will be easier to maintain.

5 - Gun-Hlstr mesh normals were flipped. They were unflipped.

6 - sit1 sequence has a vertex glitch on the upper right arm at frame 65. This happened because the vertex is parented to Bip01 Spine2 instead of Bip01 R Arm. This has been fixed.

7 - Original HL1 HD Barney has glitchy mouth vertices. I changed the model to use the The Op4 HD version, which doesn't have that issue. The Op4 HD textures are slightly brighter though.

8 - Hitboxes were tweaked. Several hitboxes were added for HD Barney fingers.

Convert the following zombie sequences to HD to replace the dummy sequences.

Note: Those sequences are unused in HL1, Op4, Blue Shift.

• busting_through_wall
• c2a3_snack_getup
• deadidle
• deadwall
• eat_to_stand
• falling
• zombie_eating
• zombie_pull_scientist

LD Op4 <-> HD Op4

• Create strafeleft_cine for scripted sequences
• Create straferight_cine for scripted sequences

Add the following HL1 grunt sequences :

• leftlegsmflinch
• rightlegsmflinch
• rightarmflinch
• leftarmflinch
• 180L
• 180R
• dragholeidle
• draghole

Add the following Blue Shift grunt sequences :

• soldier_dump
• soldier_dump_idle
• soldier_shoot_ahead
• soldier_kick

Additional information

1 - LD/HD meshes are identical except for the MP5/M4.

2 - The original model head meshes are identical. The head was merged with the body and head textures were placed as skin families. This will allow mappers to choose different skins, even with the night vision goggles.

3 - The original model does not include arms and legs flinch sequences:

• leftlegsmflinch
• rightlegsmflinch
• rightarmflinch
• leftarmflinch

The code supports playing flinch schedules so they were added.

4 - Grunt and massn have compatible skeleton but the massn's shoulders are closer to spine due to different volume. I tried to rig massn mesh on top of the grunt skeleton but the wider distance of the grunt shoulders cause the massn shoulders to stick out of the torso. Separate animations are maintained for the massn.

5 - The model strafeleft and straferight sequences are missing motion extraction LX/LY options. The grunt has those options. They were added so they can be used by AI if needed.

6 - strafeleft_cine and straferight_cine sequences have been added to be played in of5a1.bsp without motion extraction.

7 - The massn's MP5 is darker and has a different mesh compared to default grunt MP5. For consistency, the default grunt MP5 mesh has been used.

8 - The original model gun attachment is positioned at the tip of the grenade launcher rather than the main barrel. The grunt's gun attachment was used as a reference.

9 - The LD/HD MP5 bone are not at the same position. The shared HD grunt M4 has been rigged on top of LD skeleton.

10 - Custom grunt sequences were added to allow mappers to use them with massn.

11 - Hitboxes were reworked. The shared grunt hitboxes were used as a base.

12 - Some mesh UVs were reworked. Sharp edges were reworked too.

Map changes

See #27 in maps:

• All maps (Adjust Male BlackOps heads)
• of5a1.bsp (Male BlackOps Strafe left/right sequences)

• Create player model

Important:

Due to the way regular Barney model was originally made, several areas had to be reworked to get better mesh deformation in animations. This was done while preserving the model appearance.

Notes:

• HL1 and Blue Shift player.mdl data is identical, so they have the same hitboxes.
• Blue Shift barney.mdl was used for player model.
• Hands from HL1 multiplayer barney.mdl were used so they can be animated like the default HEV player.mdl.
• All bone controllers are functional.

• Create shared civilian model with:
  • default LD scientist body mesh
  • Blue Shift LD scientist body mesh
  • HD blue shirt body mesh
• Add all shared scientist sequences
• Add shared scientist bone controllers
• Add clipboard and headcrab stick bodygroups
• Use same hitboxes as shared scientist LD/HD

Additional information

LD civilian uses the same mesh as the default scientist model. The same scientist.mdl model is used for HL1 and Blue Shift LD variants.

Original HD civilian model have slightly different bone lengths. To avoid having to maintain separate SMD animations, the model has been rigged onto the HD scientist skeleton. Animations were converted so they use the correct bone length.

Example 1: HD houndeye - HL1 / Gearbox+Blue Shift

HL1:

Op4+Blue Shift

HL1 (leg):

Op4+Blue Shift (leg):

Example 2: LD scientist - HL1 / Blue Shift

HL1:

Blue Shift

In Blue Shift viewmodels, the hand meshes have several UVs misaligned with the hand texture, which causes seams.

This is visible notably in HD versions, which have a lower resolution hand texture.

LD HL1 <-> LD Op4 <-> LD Blue Shift

• same mesh
• same skin families
• same hitboxes
• same sequences for those available
• same sequences fps
• same bone hierarchy
• same textures

HD HL1 <-> HD Op4 <-> HD Blue Shift

• same skin families
• same sequences for those available
• same sequences fps
• same textures
• HL1 has less polygons than Op4 and Blue Shift
• HL1 has extra bone Bone01
• slightly different hitboxes

Add the following Opposing Force sequences from houndeye_dead.mdl :

• dead

Add the following Blue Shift sequences :

• eat_barney
• eat_barney_loop

Additional information

1 - Op4 and Blue Shift HD use the same mesh named 'lod0' which has more polygons than 'lod1' used for HL1 HD. The 'lod0' mesh has been used for the new model.

2 - The HL1 HD has a custom bone Bone01. It has been rigged on top of the new mesh so animators can use it if needed.

3 - The mouth is glitchy in sequence sleep. This happens because the mouth vertices don't follow Bip01 Head, so when the head is rotated too much inward, the mouth vertices end up sticking out. This glitch also happens in other sequences but is less visible when the model is running.

I tried to change the mouth vertices weight to follow the head, but it ended up clipping inward the chest, causing rigid mesh deformation.

It would technically be possible to make it work with multiple weights per vertex (blending), but HL1 only supports single weight.

4 - Original LD and HD use hitgroup 0 (HITGROUP_GENERIC). Correct hitgroups have been added for the new models.

5 - Several hitboxes have been tweaked.

6 - The Op4 LD houndeye_dead.mdl left arm is clipping through the ground. This model is used by monster_houndeye_dead, which only appears in of4a1 (first Voltigore encounter). It works correctly for the most part because of the terrain slope, but wouldn't work on an horizontal straight floor. I manually edited the sequence so the arm wouldn't clip through the ground.

7 - The Op4 HD houndeye_dead.mdl 'dead' sequence does not have the same pose as the LD one. I replaced it with the LD one. I slightly rotated the arms because it would clip inside the chest due to different model volume.

skeleton.mdl has no HD variant.

LD HL1 <-> LD Op4

Additional information

1 - Op4 skeleton has named bones while HL1 doesn't. The Op4 skeleton and sequences were used as a base.

2 - HL1 skeleton textures are brighter than Op4. The HL1 textures were used.

3 - Hitboxes have been reworked.

4 - Original model all use hitgroup 0 (HITGROUP_GENERIC). Correct hitgroups have been added for the new models.

5 - Various issues with the original model were fixed, notably flipped normals, uncapped surfaces, asymmetrical clavicle mesh, asymmetrical bone positions for forearms and fingers.

6 - Some bone weights were reworked.

7 - Sequences have been patched to ensure consistent bone length. Some sequences were also reworked in Blender to fix hands clipping through floor.

• Create shared Rosenberg model with
  • default LD scientist body mesh
  • Blue Shift LD scientist body mesh
  • HD scientist body mesh
• Add all shared scientist sequences
• Add shared scientist bone controllers
• Add clipboard and headcrab stick bodygroups
• Use same hitboxes as shared scientist LD/HD

Additional information

Kept head bodygroup so it does not break body change when showing needle in game.

Original HD Rosenberg uses a different mouth texture from the other scientists. For better appearance, the mesh was edited to use the same texture as the other HD scientists.

LD Op4 <-> HD Op4

• same cleansuit mesh
• same hitboxes
• same sequences
• same bone controllers
• different head meshes (LD/HD)

• Create shared cleansuit scientist model with:
  • default LD scientist head mesh
  • Blue Shift LD scientist head mesh
  • HD scientist head mesh
• Add all shared scientist sequences
• Add shared scientist bone controllers
• Add clipboard and headcrab stick bodygroups
• Use same hitboxes as default scientist LD

Additional information

The cleansuit model's arms are a bit longer than the default scientist and it has a few additional bones. The new model has been rigged on top of the default scientist skeleton. Arms have been shortened so they fit the skeleton bone lengths. This allows to use the same needle, clipboard, headcrab stick meshes.

The original model's Einstein and Slick face use textures with custom lighting, but Walter and Luther are unchanged. For consistency, new textures would need to be made but this can be handled in a separate issue. For now, all faces use the default scientist textures.

Create custom face textures for LD/HD cleansuit scientists. Apply the same lighting to all textures so they are consistent.

• Create shared newspaper civilian model with:
  • default LD scientist body mesh
  • Blue Shift LD scientist body mesh
  • HD blue shirt body mesh
• Add shared scientist bone controllers
• Use same hitboxes as shared scientist LD/HD

Additional information

See #88 Additional information for more info.

The original animations were converted to use the HD scientist skeleton. In the process, the bones were scaled to match the reference bone length. The legs now appear longer and the character's height is a bit shorter, making the newspaper clip slightly through the legs. Fixing this may require translating hands at specific frames, or manually editing the animation.

LD HL1 <-> LD OP4

• same mesh
• same sequences
• same sequences fps
• same bone controllers
• same hitboxes

HD HL1 <-> HD OP4

• same sequences
• same bone controllers
• same sequence fps
• slightly different mesh, not noticeable difference
• slightly different hitboxes

LD/HD HL1 <-> LD/HD Blue Shift

• All identical

Add the following Opposing Force sequences :

• throw_podium
• long_jump
• dead_on_stomach

Additional information

The HD Op4 model uses a lower resolution texture than HL1 HD. The HL1 HD texture has been used for the new model.

The HD Op4 model has 2 extra bones that are affected at the finger tip of the middle arm. They won't be used since they don't make a difference.

In the HD version all hitgroups were set to 0 (HITGROUP_GENERIC). Correct hitgroups have now been assigned so they can work correctly with AI TraceAttack code.

The original HD crouch sequence had several end frames missing, making the sequence shorter. I added extra frames at the end and filled the in-betweens by copying pose from other keyframes.

The original HD model collar would clip through neck in stairsup sequence. This happened because the HD collar does not connect the neck and the upper spine, and is tied to Bip01 Neck1 instead of Bip01 Spine3. As a result, the collar would rotate and clip through the neck occasionally. I reworked the collar so that it works like in LD.

Several edges marked sharp were unnecessary. They were unmarked sharp.

The HD version's middle arm has hitboxes while the original LD version doesn't. I added the HD middle arm hitboxes to the LD and tweaked several hitboxes for both LD/HD.

Barney and Otis comparisons

Note: Barney and Otis have the same bone length and orientations. They have a compatible skeleton.

Add the following Blue Shift Otis sequences :

• range_struggle
• range_fire (otis_range_fire)
• otis_dumped
• otis_dumped_idle

Add the following Blue Shift intro_otis.mdl sequences :

• intro_glance

Additional information

1 - The hand and arms textures were unconnected for rolled sleeve mesh. I connected them which fixed the texture seams around the wrists as well.

2 - Body UVs were reworked.

3 - Otis facemap UVs were originally mirrored (right side = left side). I mirrored them back so it's ok.

4 - Desert eagle UVs have been reworked to use the viewmodel texture.

5 - Gun holster bone was added so it can be used to rotate the holster mesh if needed. In addition, because Otis has a wider belly, the holster bone had to be slightly translated lateral.

To allow Barney animations to be used with Otis, the Bone03 position and rotation had to be removed from the LD animations so it wouldn't override Otis' Bone03 position and rotation. This is for eventually using a single skeleton for Barney and Otis.

The only animation I found that features additional rotation on the bone is diesimple, but I made a single commit 31d3a91 so we can restore it later if needed.

HD animations were left intact because Otis has no HD version.

6 - The original Otis range_fire sequence plays weapons/pl_gun3.wav, but I changed it to use weapons/de_shot1.wav.

The sequence is only available in Blue Shift model and is not used in game so it won't impact users that own Blue Shift, but not Opposing Force.

In addition, 5001 is replaced by 1003 (likely used to fire event).

7 - Otis fence animation is slightly different from the Barney fence one. I renamed Otis' fence sequence to otis_fence so to keep consistency with the other Barney sequences.

8 - Otis wave sequence was renamed to otis_wave to avoid confusion.

9 - Helmet hitboxes (10) were removed and the head hitbox (1) now surrounds the head.

10 - Because Otis has no custom pain sounds, the Barney pain wave files are used.

Map changes

See #27 for Otis in maps:

• of1a2.bsp
• of1a5.bsp
• of1a5b.bsp
• ba_canal2.bsp
• ba_security2.bsp
• ba_tram2.bsp

In several animations, notably Blue Shift, the scientists arms can be seen sticking out.

This happens if the arms bones are translated too far away.

Solutions:

A) Rework the mesh so that it's connected (No separate mesh for arm and body)

Would definitely solve the issue, but because HL1 only supports one bone per vertex weight, no smooth blending/mesh deformation can be made. This may become a problem in animations when arms are rotated in a specific direction.

B) Apply a translation to the arms bones to ensure they remain inside the upper body

Easier, but can affect gameplay since translating a bone will also translate the associated hitbox.

LD HL1 <-> LD Op4

• same gun mesh except with different UVs
• same clip mesh
• same silencer mesh

Additional information

1 - The LD Op4/Blue Shift gun meshes have a different texture layout than LD HL1. They also have a bit more details than HL1's. The highest resolution textures have been used.

2 - The LD/HD muzzle attachment is slightly offset to the left of the barrel. It was adjusted to be more centered.

3 - All LD variants have an additional sequence add_silencer. All HD variants are missing this sequence. Since it's the last sequence, it's not breaking.

4 - The LD HL1 Glock and hands meshes are merged as one SMD. LD Op4/Blue Shift are separate.

5 - The Op4/Blue Shift Glock mesh is slightly offset compared to HL1's. However their silencer mesh are in the same position as in HL1's so it's not correctly aligned in add_silencer sequences.

6 - The original LD HL1 hand mesh back had several textures misassigned. This has been fixed. Several mesh sharp edges were reworked.

7 - The original LD Op4/Blue Shift have a vertex along the gun side that is assigned to Bip01 R Hand instead of Bone02. This would cause side to glitch incorrectly in reload sequence. This has been fixed.

8 - LD Op4/Blue Shift hands have different volumes than HL1. The soldier and Blue Shift hand meshes had to be rigged to be able to be positioned in a way they would not clip through gun.

9 - HD HL1/Op4 reload_noshot animation does not animate the clip. HD Blue Shift does. The HD Blue Shift animation has been used.

10 - Silencer mesh has been added to HD variants. Note that the HD animation might be done later. See #17 .

11 - LD clip_reference.smd is identical to v_desert_eagle clip_reference.smd. Both models now share the same clip mesh.

12 - In LD/HD reload animations, the clip orientation is turning around, which can make players see through the model since it has no back face. This has been fixed.

13 - The new models were tested in game. Every sequence has been tested except holster and add_silencer, which
are unused in game. They have been reviewed in HLAM and are expected to play correctly if ever used.

LD HL1 <-> LD Op4

• Op4 has additional bodygroup 'heads' with cellphone
• same mesh

• Add suitcase bone controller

Add the following Opposing Force sequences :

• cell_idle
• cell_away
• working_nuke
• push_button

Additional information

1- The LD HL1 mesh has a few smoothing issues at the back of the neck and glitchy mouth mesh deformation. The Op4 mesh had these issues fixed for the most part, so I used the Op4 mesh.

2- Original LD/HD all use hitgroup 0 (HITGROUP_GENERIC). Correct hitgroups have been added for the new models.

3- Op4 LD cell mesh included the entire Gman mesh. It was removed so only the mesh cell is kept.

4- Because the right hand is animated to hold the suitcase in all sequences, the suitcase is not placed in a separate bodygroup. It will always be present.

5- 'heads' bodygroup has been renamed to 'items'.

6- A bone controller (3) has been added to allow opening the suitcase if needed.

7- Hitboxes have been added to suitcase. They use hitgroup 0 so coders can override behavior if players hit the suitcase.

8- The hitboxes at the lower portion of the coat were removed and a single pelvis hitbox is used instead.

9- In the original HD push_button sequence, the right hand fingers rotation were missing. The animation has been patched with rotations from another sequence so they remain tight.

10- Several end frames of HD sequences yes; no; lookdown have been cut to fit the original LD sequences durations.

The Osprey has no HD version.

HL1 <-> Op4

• same mesh, but Op4 has wheels for take_off sequence
• same hitboxes
• same bone controllers
• same sequences and fps for those available
• same textures, but Op4 has multiple texture sheets

HL1 <-> Blue Shift

• Identical

Add the following Opposing Force sequences :

• on_tarmac
• take_off

Additional information

1- The HL1 Osprey texture layout is different from Op4. The Op4 Osprey is used as a base since the other Osprey variations use pretty much the same Op4 texture layout.

2- The HL1 rotor sequence origin height is different from the one in Op4. This is because the reference's bone 'Osprey' is in a different position. The sequence has been fixed so it's in the same expected position as in the original HL1.

3- The original Op4 Osprey hitboxes are offset below and rotated 180 degrees around Z axis. This is because the 'Osprey' bone is rotated in the same way and is in a different position. I reworked them so they are correct.

4- The HL1 and Op4 rotor sequence have the same number of frames and same fps, but the blades rotate faster in the Op4 version. The Op4 speed is used.

5- Left wing bones were originally suffixed R while right ones were suffixed L. Bones' names have been swapped to avoid confusion.

6- Hitboxes for all 3 wheels have been added with a specific hitgroup for each, in case modders want to add behavior when wheels are hit.

7- The cockpit hitbox originally only covered half of the cockpit area. This has been widened to cover the entire cockpit.

8- Existing hitboxes have been tweaked and new ones were added.

9- UVs of the floor, ceiling, sideways of the middle boarding interior were reworked and are now correctly aligned.

Osprey variants

I checked the following models:

• blkop_dead_osprey.mdl
• blkop_osprey.mdl
• blkop_osprey_bodygibs.mdl
• blkop_osprey_enginegibs.mdl
• blkop_osprey_tailgibs.mdl
• crashed_osprey.mdl
• dead_osprey.mdl
• mini_osprey.mdl
• mini_osprey_bodygibs.mdl
• mini_osprey_enginegibs.mdl
• mini_osprey_tailgibs.mdl
• osprey.mdl
• osprey_bodygibs.mdl
• osprey_enginegibs.mdl
• osprey_tailgibs.mdl

I made a list of all aspects of each model across all 3 games. Opposing Force has a couple of custom Osprey models such as crashed_osprey.mdl, mini_osprey.mdl and the BlackOps variants.

I checked the models and some have several texture sheets (unwraps) incompatible with the current Osprey. Some also have glitchy appearance due to improper UV setup. In addition, BlackOps variants have inconsistent textures across their counterparts.

Standardizing the textures and meshes between each Osprey model requires a considerable amount of work. BlackOps textures could be remade by desaturating the military Osprey texture but this should be done after all other variants standardization is finished.

Although BlackOps Osprey entity exists in code, it is unused in game. Since crashed_osprey.mdl and mini variations are only used in Op4, and no other model beside osprey.mdl is used, standardization for the others can be done later.

Existing hitboxes have been reworked. New hitboxes were added to spine, head and fingers.

The changes have been applied to all variants:

• Civilian coat scientist

Note: Cleansuit scientist is unchanged because it uses LD scientist skeleton.

The PCV suit has no HD variant.

Additional information

1 - Op4 has an additional submodel entry in which the suit is positioned on the back.

2 - Blue Shift's w_suit.mdl is the HEV suit. No custom model is needed.

Low definition:

High definition:

For converted sequences, and because LD/HD meshes have different size and volume, the hands can sometimes end up clipping through the body.

This also happens with sequences that were converted from LD -> HD, in which the tie always keeps the same transform as the reference and can occasionally clip through the body as well. The sequences with ties clipping are not used in the original games so this can be fixed later.

Solutions:

A) Manually edit the animation

Can be easy or difficult depending on the animation. The elbow also needs to be adjusted to ensure the length of each bone is preserved.

When importing an SMD animation, each frame is filled with the position and rotation. This requires carefully moving the bone and ensure they follow correctly across all frames otherwise this will cause animations to jitter.

When building an animation from scratch, keys are set at specific times and interpolated between each. When exporting to SMD, this information is lost.

B) Automatically apply transformations to fix the position and rotation

Same as A).

The headcrab has no HD version.

Add the following Op4 sequences :

• eat_ground
• jumploop

Some LD and HD models have different skeletons, different animations, different hitboxes.

The main objective is to make both LD/HD use a common skeleton, same animations, same hitboxes.

Reasons:

• Ease maintenance of models
• Avoid confusion for mappers and potential issues that arise from using different sequences (1)
• Ensure both LD/HD have same sequence durations (2)
• Ensure both LD/HD use the same hitboxes. (3)

(1) For example, LD and HD scientists don't use the same arm when playing give_shot sequence. The needle is not on the same hand. Depending on what the mapper intended, this can look wrong in LD/HD if other bodygroups are enabled (clipboard/headcrab stick).

(2) Having different sequence durations between LD/HD can cause discrepancy in gameplay. Both variants may end up too soon or too late depending on what the mapper intended.

(3) The HD model is just a graphical overhaul. It shouldn't affect gameplay.

Tentacle has no HD variant.

LD HL1 tentacle2.mdl <-> LD Op4 tentacle2.mdl

• same skeleton
• same hitboxes
• same attachments
• same sequences and fps, but level 1,2,3 sequences altitude is different in Op4
• same mesh
• same textures

LD HL1 tentacle2.mdl <-> LD Op4 tentacle3.mdl

• same hitboxes
• same attachments
• same sequences and fps, but level 1,2,3 sequences altitude is different in Op4
• same mesh
• same textures

LD HL1 tentacle2.mdl <-> LD Blue Shift tentacle2.mdl

• Identical

• Create default tentacle2.mdl
• Create tentacle2_lower.mdl with Op4 sequences that have different altitude

Additional information

1 - Op4 includes a custom tentacle model 'tentacle3.mdl', which is a slight variation of tentacle2.mdl but with different altitude for level 1,2,3 sequences.

2 - The Op4 tentacle2.mdl Level 1,2,3 root bone is positioned at a different altitude, making the sequences incompatible with the HL1.

3 - The Op4 tentacle has an additional spawnflag 64 'tentacle3' set and the original game DLL contains a string 'tentacle3.mdl', which leads me to believe that a specific model is picked whether or not this spawnflag is set.

4 - HL1 identical sequences have been reused when possible. I tested in game with the custom tentacle2_lower.mdl as tentacle2.mdl and haven't found issues with the sequences.

Additional information

1 - LD HL1 sequences (all) are different compared to Op4/Blue Shift. Op4 and Blue Shift sequences are identical.

2 - The LD HL1 viewmodel is rather unstructured and does not appear to be made on top of the regular skeleton rig. In addition, the LD Op4/Blue Shift animations are more polished than the original HL1 so the Op4 animations and skeleton were used as a base. The HEV Python hands meshes were used.

3 - LD Op4/Blue Shift gun attachment was offset from the barrel tip. This has been fixed.

4 - LD Op4/Blue Shift deploy_2 seems to be identical to first 12 frames of longidle. It does not represent a draw/deploy animation. It was removed.

5 - Because Gordon's fingers are thiner than Adrian or Barney, the thumb was clipping through grenade launcher and ammo clip in various sequences:

• longidle
• reload
• shoot_2
• shoot_3

The animations were manually edited to fix the issues.

6 - The new models have been tested in game. No issue has been found.

Additional information

1 - HD Blue Shift DC_soldier_torso.bmp is 256x256 while HD HL1 is 128x128. The highest resolution texture has been used.

2 - HD HL1 mesh DC_soldier_reference.smd has more vertices than HD Blue Shift.

HL1 : 466 verts
BS  : 307 verts

The highest resolution model has been used.

3 - The original LD HL1 dragleft and dragright sequences are swapped, which appears incorrect in game while the HD have the correct side. I swapped the 2 sequences and tested in game to ensure it works in HL1 (c2a3e) and Blue Shift (ba_outro).

4 - In Blue Shift custom sequences, the hand is sticking out of the forearm. The sequences have been fixed so the correct bone length is used.

5 - In the original body mesh, forearms and hands were disconnected.

I tested a few times with different vertex weight setup but the result is always glitchy when forearm and hands are too much rotated. This is unavoidable since HL1 engine does not support multiple weight per vertex.

They will be kept separate.

6 - The grunt neck vertices were weighted to head bone, causing it to stick out of the body when the head bone was too rotated. I weighted them to Bip01 Spine3 so they stay on the torso.

7 - LD/HD model UVs were reworked.

8 - LD/HD hitboxes were reworked.

9 - HD cliffdie sequence had missing cut frames. The LD animation was converted to HD so it can play the full sequence.

10 - The right foot was doing a full rotation around the Talus in the original LD and HD WM_moatjump sequence. This has been fixed.

• Soldier hand

Additional information

1 - HD HL1 and Op4 v_python_Reference.BMP are higher resolution than in Blue Shift. The highest resolution has been used.

2 - LD HL1 has different gun mesh UVs compared to Op4/Blue Shift.

3 - LD Op4/Blue Shift and all HD variants are missing the reload sound event. This was added.

4 - LD Op4/Blue Shift python_speedload.smd mesh is messed up. The LD HL1 mesh is used.

5 - HD gun attachment 0 is offset compared to LD variants. This has been fixed.

6 - The new models have been tested in game. No issue has been found.

HL1 HD <-> Blue Shift HD

• Same/Identical meshes
• Same hitboxes
• Same sequences for those available
• Different sequence FPS

Additional information

1 - Slick head is used as 4th model head. Rosenberg will be moved to a separate model.

2 - HL1 LD scientist mouth bone controller max value is 20 while max in Blue Shift is 16. This will work as long as the max value is used when calling SetBodygroup()

3 - In Op4 crouch_idle sequences, the hands are a bit offset away from the head. The HL1 corresponding sequences will be used since they have correct hand placement.

4 - In Op4, the sequence fall_elevator is identical to fall in HL1. The sequence fall.smd is reused without changing the sequence name. HL1 and Op4 now use the same model. fall_elevator is unused in Op4.

5 - In Op4 HD, the fifth head (clipboard) uses Glasses while the LD uses Einstein. For consistency, Einstein is used since the LD came before HD.

6 - The following sequences were not available in HL1 HD and were converted from HL1 LD:

• scicrash
• scicrashidle

7 - The following sequences were empty in Op4 HD and were replaced by those in HL1 HD:

• dryhands
• lean

8 - The following sequences were empty in Op4 HD and were converted from Op4 LD:

• of1_a1_cpr2
• cpr_gesture1
• cpr_gesture2

9 - LD -> HD sequences do not animate the scientist tie in HD. The tie can sometimes be seen clipping through the body. Fixing this issue requires manually animating the sequence. At least, those sequences are not used in the game so this can be fixed later. See #28

10 - Blue Shift skeleton hierarchy is different from normal HL1 and has different bone length for the most part. When converting from Blue Shift LD -> HL1 LD, the bones length is recalculated to use the target length (HL1). In some animations, the hands and feet may not entirely match the position of the original animation. In almost all situations, the pelvis is translated to the original animation pelvis position, then the following adjustments are made for specific sequences:

• Ground animations: The pelvis is translated so that the feet are positioned halfway between both feet in the original animation.
• Sitting/leaned animations: Feet positions can be translated upward if they clip through the ground.

In addition, for converted sequences, and because LD/HD meshes have different size and volume, the hands can sometimes end up clipping through the body. Fixing this may require translating hands at specific frames, or manually editing the animation.

Used for documentation.

Because shared models need to play different sequences that have the same name across 3 games, the following adjustments need to be made to maps.

All maps

Change weapon_shotgun angles (Opposing Force and Blue Shift only)

Change:

• angles to Y Z X where Y = original pitch, Z = original yaw + 90, X = original roll + 180

Note: because the mesh is not fully centered along Z axis, rotating around the X axis (Roll) can cause the model to clip through the ground in some cases.

Some maps in Op4 and Blue Shift use "angle" keyvalue to set the yaw.

Change:

• angle to angle + 90

Adjust Male BlackOps heads

For all monster_male_assassin do the following:

With keyvalue "head" "0" (White)

Add:

• skin = 0

With keyvalue "head" "1" (Black)

Add:

• skin = 1

Change:

• head to 0

With keyvalue "head" "2" (Black with thermal vision)

Add:

• skin = 1

Change:

• head to 1

• Use same hitboxes as shared scientist LD/HD

Additional information

The head mesh UVs have been reworked to reduce seams but there still are a few minor seams along the front side of the neck, which likely happens because of the texture border introduced by linear filtering. With Point filtering, there are no visible seams.

The original model has no mouth bone controller. I added it so modders can make the model speak. LD Blue Shift variant uses the corresponding mouth and teeth textures to keep consistency.

The original model has a badge on upper torso. It was removed for the following reasons:

1. The badge would clip inside the body if the associated spine bone would rotate too much. To make it functional, it would require adding an extra bone, tie the badge to this new bone, and animate the bone in each sequence to ensure it works. This in itself would be a lot more work.

2. To make it consistent with other LD models since the other LD scientists don't have badges.

The badge is kept in the HD variant.

@SamVanheer

While reworking mesh UVs with viewmodels I found texture coordinates were slightly offset in HLAM compared to the ones in blender. After investigating StudioMDL source code, I found potential issues I wish to discuss.

To illustrate the issues, I created a simple case with a textured cube. The texture is low resolution because it's easier to show the issue. The texture is 37x35. On purpose, I made the texture size not power of 2.

Here is the unwrap sheet in blender :

Here is the unwrap in HLAM after compilation by unmodified StudioMDL :

In this case the texture coordinates are slightly offset up and left for the most part. On higher resolution textures, this could be more.

Texture coordinates are UVs mapped to pixels. For example given a 64x32 texture, UVs (0,0) (0,5,0.5) (1,1) would map to (0,0) (32,16) (64,32).

When the code calculates the texture coordinates, it subtracts 1 pixel from texture width and height, which results in at least 1 pixel lost.

https://github.com/malortie/custom-hl-viewmodels/blob/b95b433aeaacdb231f0bc0a8cbee7a53b947267c/utils/studiomdl/studiomdl.c#L1407-L1408

When getting the skin width and height, it adds 1, probably because of the previously subtracted pixel but I think it's incorrect.

https://github.com/malortie/custom-hl-viewmodels/blob/b95b433aeaacdb231f0bc0a8cbee7a53b947267c/utils/studiomdl/studiomdl.c#L1528-L1529

After fixing the aforementioned lines, the resulting texture coordinates are now correctly aligned with the texture.

There was still extra space on the right and I believe this is coming from the following line in GetSkinWidth(). When power of 2 is disabled, the code returns the width as a multiple of 4.

https://github.com/malortie/custom-hl-viewmodels/blob/b95b433aeaacdb231f0bc0a8cbee7a53b947267c/utils/studiomdl/studiomdl.c#L1498-L1501

It should return rawsize unchanged like in GetSkinHeight(). Later in the code, the width is eventually adapted to be a multiple of 4 for BMP so it shouldn't be changed before.

https://github.com/malortie/custom-hl-viewmodels/blob/b95b433aeaacdb231f0bc0a8cbee7a53b947267c/utils/studiomdl/studiomdl.c#L1545-L1546

After fixing rawsize, the texture shows no extra space which is likely the expected result :

I pushed the changes in the branch texture-coordinate-issue. If you could take the time to review the changes and provide feedback, this would be appreciated.

See the following files :

• bin/studiomdl_fixed.exe (Fixed version of studiomdl.exe)
• modelsrc/cube/compiled_with_original_studiomdl/cube.mdl (Offset texture coordinates)
• modelsrc/cube/cube.mdl (Fixed texture coordinates)

Additional information

Because texture coordinates are stored as integers and UVs are floats, the decimal part of the UVs is discarded so can result in a pixel offset farther than it's intended location. I used lroundf to ensure the nearest integer value is returned.

The loader has no HD variant.

HL1 <-> Op4

• same hitboxes
• same mesh
• same textures, but Op4 has different crate textures
• same sequences and fps for those available

HL1 <-> Blue Shift

• Identical

• Add Op4 crate texture as new skin

Add the following Opposing Force sequences :

• 45_left
• park
• blocked
• freed
• dropbox
• pivotback

Additional information

1- freeze sequence is identical to heroidle. It was removed.

2- Original LD/HD all use hitgroup 0 (HITGROUP_GENERIC). Correct hitgroups have been added for the new models.

3- Hitbox 'body' was covering unnecessary area. It was removed.

4- Several hitboxes have been reworked.

Notable hitgroups:

• Crate: 0
• Rear left leg: 8
• Rear right leg: 9

5- Op4 Loader crate texture is different from HL1. It has been put as a second skin.

Map changes

See of1a4b / Loader in #27.

Various models, including Barney, Otis and Player have issues in sequences where the pelvis and legs are rotated too far.

This issue is visible in barney.mdl and otis.mdl sequences:

• cowering
• otis_dumped
• otis_dumped_idle

One way to improve it would be to split lower pelvis vertices and parent them to each respective leg.

• Player weapon models (p_.*)
• View models (v_.*)
• Weapon & object world models (w_.*)

Because HL1 models don't have vertex blending support, a vertex can only be assigned to one bone. Because the pelvis root vertex is often parented to either Bip01 or Bip01 Pelvis and never to one of the legs, it stays in place which results in visible mesh deformation when legs are rotated away.

Solutions:

A) Parent the pelvis root vertex to one of the legs but this can also cause mesh deformation in certain models when legs are rotated away from each others. (Easiest)

B) Create an edge loop around the pelvis root vertex to allow each leg to have their appropriate vertex. The original root vertex would then have to be removed. The edge loop can be made extremely thin to make it look as if there is still one root vertex.

Solution B) is preferable.

Tests:

Additionally, custom animations that animate the legs in different positions could be made to be able to quickly view if any issue arise after that once all meshes are fixed. Those animations would not be included in the release models.

• (Optional) Create custom animations that rotate legs in different positions
• (Optional) Create test models for use with the custom animations
