I had posted a topic earlier about this issue, but I never really got any answers to my question. My problem is, that I'm using VBOs to render the polyes of my maps, and this complicates things because I can't alter the texture coords in a fast manner this way. You see, I use detail texturing ingame, and for these to work properly I need to multiply the texture coords for the texture unit I have my detail texture on, but the only way I could do this so far was by telling OpenGL to scale the texture unit using glScalef, but this is rather slow, and I'd like to know if there's any other command that lets me modify the texture coord? I already tried loading a new texture matrix, but that's just as slow. Thanks.

Nevermind, I seem to have found a solution.
