darimc,
Piece of cake. I don't know what 3D Model program you're using, so I'll keep this generalized.
1. Work your model...resize, animate, whatever.
2. Remove all material & texture references that might exist.
3. Reassign the textures to the specific groups or vertices.
4. Export your model as an .x file. Place all of the textures used in the same folder as the model.
5. Open the .x file in notepad. Do a search for the work texture. What you're looking for is a line that points to each of the different textures that you used with the model.
6. Once found, everything between the "" will be the path to the texture file. Shorten or add a name here that matches the texture files in the model's folder. When you have examined and updated each of the texture paths, save and close the file.
7. When you create an .fpe file for your model, simply leave the textured = line blank...don't enter anything. When the entity is loaded into FPSC, the texture information encoded in the .x file will be read, and the textures will be applied.
You should be all set. I hope this helps.
Thanks,
Seth Black
