I've been learning how to mod, and learning a lot but I'm having trouble getting textures to work in-game. I've been using XSI Mod Tool and GIMP. I have read the documentation that comes with the tools for modding. I have the DDS plugin for GIMP. I can get models to load in-game, but they are untextured, even though I have a -cl.dds texture attached. After doing some tests, I've narrowed the problem down to the texture file; the mesh file appears to be fine.
Any ideas why this might be happening?
