RUNNING ENGINE ON WIN32/WIN64

Copy StormEngine2.exe into a FolderOfYourChoice/
Copy base/ folder into FolderOfYourChoice/ where you copied StormEngine2.exe previously
Run StormEngine2.exe

Note: legal screen is disabled in debug builds. Intro video can be skipped by pressing a key, a gamepad button or moving mouse in any build.

BASE ASSETS PACKAGE (for testing)

Base assets package is offered by Yuizaki from idTech4 discord (a mix of Phaeton assets, Yuizaki's assets and assets made by other community member(s) ):

OVERALL CHANGES AND ADDITIONAL FEATURES

(in addition to existing set of features of the original engine)

Flexible build system using CMake
Linux support (32 and 64 bit)
Win64 support (including Win64 tools)
OpenAL Soft sound backend primarily developed for Linux but works on Windows as well
PNG screenshots support
Soft shadows using PCF hardware shadow mapping
True 64 bit HDR imaging
Soft (feathered) particles
Gloss maps support
Oblique view frustum (for proper reflections in the water)
High resolution RoQ videos playback
Blurry real-time reflections
Image based bloom ("glow")
Image dithering (eliminates banding artifacts on gradients)
Underwater view warping
Material flag to force images to be kept in RGBA format (unocmpressed)
Full set of built-in tools for Win32/Win64 platforms (with various fixes and improvements)
envShot cmd to generate cubemaps
Higher quality YCoCg "scaled" DXT5 compression for diffuse images (from GIMP DDS)
YCoCg "scaled" DXT 5 compression for skyboxes and cubemaps (yields high quality skies with minimal artifacts and no banding)
Demo recording and playback
LOD for static and animated entities (although not for map brushes)
Mods loading and packaging into .resources
Wheeled Vehicles (player driven and self-driving)
Automatic overwrite of outdated binary files when auto-authoring updated content
Fixed inlining (embedding) of static meshes into .proc while retaining collisions
Map loading progress indicator
Texure compression progress indicator
Collision fix for large coordinates
noSpecular option for lights now works (fill lights should use it to avoid unnecessary specular highlights)

KNOWN ISSUES

DoomScript debugger doesn't quite work in 64bit build

A WISHLIST OF FEATURES (to be added to the engine by some programming wizard :) )

~~Fix vehicles (savegame crash fix; networking)~~
8-way texture blending using vertex colors with transition masking using height maps
Equirectangular skybox (in addition to existing 6-image cubemaps)
Refine LOD solution (make it a bit more performant; add support for skeletal meshes)
Distance culling (not render meshes past certain distance)
Foliage shader with simple wind deformations (including using vertex color to anchor mesh and create gradient rigidity)
Mesh instancing for static meshes (kinda like ISM/HISM in UE4)
AAS on meshes (to be able to have navigation built on mesh terrains)
Save/load game multithreading (to eliminate hiccups/freezes when performing saving/loading in-game)
Improve Lights Editor to allow spawning/deleting/moving/saving lights in-game
DoomScript nativization (optional, to improve performance)
Reverb zones (XAudio2 supports reverb afaik)
Native multiplayer coop
Headless dedicated server
Master server app
Improve shadowmapping (particularly cascaded shadowmaps on huge levels)
Replace current texture compressor with fast BC7 compressor
Replace all legacy OpenGL 1.x stuff with OpenGL 3.3 (or whatever base standard is nowadays)
Parallax-corrected cubemap reflections (with support for equirectangle textures; or better yet reflection capture entities)
SSAO
Light shafts
Good looking and (relatively) fast POM shader with self-shadowing
Volumetric fog supporting shadows
Replace SWF renderer with SVG renderer

AUTHORING OF BITMAP FONTS

Generation of new bitmap fonts is somewhat convoluted process, no thanks to Doom 3 BFG engine. To be able to generate engine compliant bitmap fonts, please follow instructions below. The process used to work smoothly back in the days and hasn't been tested in 2021.

Download BFGFont app (based on https://github.com/Zbyl/BFGFontTool by Zbyl): https://drive.google.com/file/d/1P-o0gyZocH5oK_GIpT7TAr-Zzrs6w4Dl/view?usp=sharing

Install your favourite font (licensed or open source licensed; beware of "free" fonts found on the Net) into the system OS.
Generate bitmap font and image atlas using BMFont app (Bitmap Font Generator; v1.13 was tested) using settings file located in utils/BFGFont/bmfont_settings/ (don't forget to choose font)
Save bitmap font as "48", rename 48_0.tga into 48.tga and edit 48.fnt to adjust image name.
If there are 48_1, etc. image atlases present, adjust image resolution in BMFont settings - there can only be one atlas.
Run BFGFontTool 1.2 from utils/BFGFont/ and generate BFG font using .fnt file we just created
Copy 48.dat, 48.tga, fontimage_12, _24, _48 into base/newfonts/fontname/ (fontname can contain smallletters, numbers and _ )
Rename fontimage_12, _24, _48 into old_12, _24, _48
Edit base/strings/english.lang and add definition for new fonts at the beginning of the file, after "#font_" line. For example, "#font_ubu" "ubuntu". That will remap font definition in .gui UI from [font "fonts/ubu"] to a new font "ubuntu". Note that "#font_XXXXX" seems to be currently limited to 5 symbols after "_".

NOTE: unfortunately the README that came with our copy of the library has been lost, so the one from release 6b is included instead. There are a few 'glue type' modifications to the library to make it easier to use from the engine, but otherwise the dependency can be easily cleaned up to a better release of the library.
