Sorry to bother U again.

I need to import some static meshes from UE4 to Blender.
And I wanna know....Does Workspace have the functions that ...

1.Can the plugin import the basic texture with static mesh (I need to import a lot of meshes. The number of tex is very large)
2.Can the plugin remember the positon/rotation/scale information in UE4 level and make it in Blender scene when I import them?
3.There is a lot of assets and several levels in my UE4 project. When I connect Blender and UE4, the Asset list is very long in Workspace in blender. Can I only choose the part which only shows in my current UE4 level to show in the Asset list in Workspace？

Thanks for the attention.

Fix ASAP

just some improvement

Hi

I installed the addon in 2.91 (Windows) and trying to use it with Unreal 4.26 (Windows) but this is what I am getting when I connect to Unreal and when I try to update the asset list in Blender

Unreal has Python installed and remote execution is enabled in the project.

location: <unknown location>:-1
Error: Python: Traceback (most recent call last):
  File "C:\Users\USER\AppData\Roaming\Blender Foundation\Blender\2.91\scripts\addons\UE4Workspace\UE4WS_ExportOptionImportAssets.py", line 159, in execute
    AssetsList += json.loads(output["output"][0]["output"])
IndexError: list index out of range

location: <unknown location>:-1

The title says it all.

I installed the plugin, successfully.

and....I can find the plugin in the right root folder.

But I can't find it in the Add-ons list

My Blender version is 2.92. I downloaded it from steam. My other plugins can work normally. Thanks for your attention. I hope my bad English won't bother U...orz. Thanks a lot

just some improve note

there's currently 2 idea to improve bake action speed

• using export and import
  let blender FBX export bake the animation and import FBX of result the animation
  • pros
    using like export retarget animation without bake
  • cons
    keyframe = performance speed to import
• using keyframe_insert INSERTKEY_VISUAL
  not tested yet because the keyframe data store the previous data and can break the tweak transform data

basically remote_execute.py does not support many output character from unreal engine console

I'm think to store assets list in a single file

just like rigify does

add level of detail system

About export fbx file (for UE4), how to set scale(100) for all mesh?

Plan

• add bone twist (done)
• generate rigging
• control rig in pose mode for animation

Bug

• twist copy wrong prop if mirror x axis enable

I have plan to rewrite and deprecate some feature :

• Retarget Animation -> move to https://github.com/anasrar/ReNim
• export profile
• Rigging

and min. requirement blender 2.91 and unreal engine 4.26

Really hope this cool plugin can support blender3, blender3 can not connect to unreal engine 4 currently.

in unreal engine is possible to create socket using clipboard buffer and just paste it on skeleton tree
clipboard buffer structure

SocketCopyPasteBuffer

NumSockets=1

IsOnSkeleton=1
Begin Object Class=/Script/Engine.SkeletalMeshSocket Name="SkeletalMeshSocket_0"
SocketName="sword"
BoneName="hand_l"
RelativeLocation=(X=0.0,Y=0.0,Z=0.0)
RelativeRotation=(Pitch=0.0,Yaw=0.0,Roll=0.0)
RelativeScale=(X=1.0,Y=1.0,Z=1.0)
End Object

Reference

https://docs.unrealengine.com/en-US/API/Runtime/Engine/Engine/USkeletalMeshSocket/index.html

Concept

calculate relative transform using matrix in blender and copy transform value to clipboard

for now it just a plan and doesn't any prototype yet
some notes will be update
the plan is importing asset to blender from unreal engine (static mesh, character, and animation)

planing any feature for better custom collision workflow

3D Model: Japanese Lion By Joel

Planing

• optimize make custom collision
• move custom collision into collections
• make custom collision semi transparent green for better visibility
• custom collision picker from mesh

when you try to export temporary and with create material setting, unreal engine can not handle remove file because still using for compiling material

How can i modify exported name same as blender object name?

How can i modify exported name same as blender object name?

what should I do?Or use some setting?

• Workflow: i.e. A real-time link from Blender to UE is like unity's meshSync plugin
• Description: i.e.

Hi！I recently noticed that Unity's MehSync plugin has been able to sync most of Blender's data in real time. Just bone data may not be perfect for games, but it's almost done with USD data transfer.

The USD Hydra plug-in developed by AMD is currently the only way to dynamically link USD to Blender. However, the supported data is too few. Blender's meeting last week was still discussing the follow-up development route of USD, so it is difficult to make progress in the short term.

So I'm really looking forward to a plugin like Unity's MeshSync that links to Blender in real time, which is a breakthrough for both game development and film production, allowing almost any Blender user project to seamlessly connect to UE, even if they've only learned the basics of UE for five minutes. 

Hopefully you will be able to develop a similar real-time synchronization feature before Blender fully supports USD (which I think is at least a few years away), thanks for your efforts!

Hi I installed blender add-on and enabled scripting and remote execution in unreal but when i press the button in blender : "Update Assets List" this error shows up and no asset is listed.

Thanks in advance.

in unreal:

PS: blender version: 2.90.1 unreal: 4.26.1

ue4.26.2
blender 2.83.3

texture can't export

blender2.93.100
can't connect to ue4

add retarget animation, for now only support mannequin and mixamo skeleton.
any information will be update soon

because groom hair import still not stable enough in unreal engine python or blueprint (more better because can pop up import settings window) that causing crash.

Thread : https://forums.unrealengine.com/development-discussion/python-scripting/1846215-groom-how-to-assign-hair-group-preview-in-groom-import-options-to-prevent-crash

so this is recommend setting for import.

some note improvement

I get this error

I want to get canopyframe.fbx, but exported canopyframe_1.fbx.
So....I miss sth?

Allow make socket from blender for unreal engine

• static mesh
• character (skeletal mesh)
  UE4 Python still not support add socket using python for skeletal mesh

first approach for static mesh :

prototype layout in object panel

• new socket location on 3D Cursor
• socket parent is current object (mesh or bone)
• socket in another collection
• socket using empty arrow for better visibility
• attach object to socket

I get this error when exporting to UE4 but not FBX.
