I DID remember the blue faces. And I don't use multiple textures.
Ok: I'll explain more detailed:
1: I open SketchUp and make a simple box for a test.
2: Then I export my model into .3ds.
3: Then I open 3Dobject converter and convert it to .x
4: Then I open LithUnwrap, open the model with it, select all the mesh and then I go to tool/uv mapping/decal. After this, I set it to 'front'. Then I click OK.
5: I see the shape of my model and I save the model as .x and the UV map as .tga.
6: After this, I open the UV Map, and draw simple green lines for a test.
7: Then I copy the model and texture to FPS Creator/Files/Entitybank/User
8: After this, I open 'Make entities from .x files' AKA entitymaker and do my tricks.
9: After this, my job is to take snapshot but I notice that the texture is not in the model
10: I open FPS Creator to see if it could be there but the texture isn't there.
Hope this was enough
