I'm unable to reply to your PM so posting here instead. It's a great idea for us to help each other and I can certainly share any 3d buildings/scenery models, that we create for our Warhammer Dark Omen 2 mod and for our Unreal Engine Dark Omen Reborn remake project.
is it cool to discuss extracting .diffuse & .geom files ? If not then please remove the following ->
I've now got an extended version of W4kfu's diffuse_parser.py that can successfully extract any .diffuse file from \Art2\assetdb\decals but only if it has square dimensions ...
your program looks awesome! I had recently asked W4kfu to extend his diffuse_parser into a converter but looks like you have already. Please let me know when you get a chance to release it.
