Well, I've made some hacks on Doom3.exe in order to "convince" it to support 3Dc format (ATI1/BC4 & ATI2/BC5). Of course, all other formats still should work as well. I must admit that I haven't tried these hacked Doom 3 executables with 3Dc normals, but I've ran both Doom 3 and TDM with them, and everything seems was ok. Does anyone want to try?
If it so, please notice that my archive
consists of two executables: Doom3_LATC.exe and Doom3_RGTC.exe. Jean Michel Paul van Waveren, id Software, and Ignacio Castaño, nVidia, think that LATC is more convenient than RGTC in some cases
, so I provide both versions: LATC and RGTC.
I must warn you: there is no warranty that these executables will work as it should, so use it on your own risk. And because those two OpenGL extensions (GL_EXT_texture_compression_latc/rgtc) are required a DX10-compatible hardware (ATI/AMD Radeon HD 2xxx and higher, nVidia GeForce 8xxx and higher), please don't try to run my hacked executables on a DX9-compatible hardware and earlier.
