Hi, is it possible to apply multiple textures to an object? An example Im thinking: take a skybox, apply a starfield layer to it initially, then apply some other layer, like a nebula. Would this have a rendering impact? Or affect framerates Any thoughts Luco

Yes, it is possible. In opengl you will need to use the ARB_multitexture extension. I've just started with ogl, so I'm not an expert, but I think that it shouldn't affect performances too much (expecially considering other effects): in any case you wouldn't have to worry about framerates impacts, in my opinion.

For DirectX, take a look at Texture Blending using the FFP. It's also possible to write some simple multi-texture shaders.
