  • I've imported an obj file and I've add a texture. What is the way to add another texture? For example the character eyes one?

    A solution is it combine all texture in just one.

    In this tutorial everything is explained: youtube.com/watch

    ...in according whit this:

    Texturing should be done at the mesh level, with UV's exported as part of the .obj file. That's the way I did it in the tiny tank demo, and the way it should be done for any game. A single .obj mesh can be comprised of many geometric primitives, all sharing the same texture.

    You need to UV unwrap your mesh, then create a texture which contains any graphics you want (all in the same image), then map the individual polygons to the respective areas on the texture map. This can be done in most 3D programs. (I recommend blender, it's free) Alternatively, you can create multi-part objects on the Q3D level (instead of the mesh level), which each have their own materials. This isn't optimal though (and should not be done in any real game): it's highly recommended to bake as much geometry as you can into single meshes, to have minimal separate objects on the Q3D level, to minimize cpu bottlenecking.
