I guess the most of you guys know this. I wanna make a tecture for a piece of clothes of for a person. HOW? is there some predecided size of the picture?

There are a gadzillion tutorials on this subject. PhilC has one of the best. Check here for tutorials. Check Poser Arcana also. And check the links on the bottom-right for sites that have tutorials. To quickly answer your questions, though. You'll need a 3D object that contains UV coordinates (vt for .obj)representing the clothes (which it sounds like you have already). You'll also need a texture template to draw onto to make the texture for the clothes; this is the best approach. There is either an existing texture template (Daz3D supplies them with all of their models) or you will need to get UVMapper and make one yourself (which isn't very difficult if you just want the default UV's used). The size of the image really doesn't matter - uh oh :). The bigger the better up to a certain extent since you'll get better resolution from a larger image. But, of course, if it's ridiculously large (like 10MB), your rendering will go very, very slowly. Good luck and have fun with it!! Kuroyume
