Hello I've tried but i can't store texture coordinates in obj format for example i want that a box take from a single texture diferent parts, for every faces to be diferent, i do that and when I render to texture all goes fine but when I export the obj file, the texture coordinates are wrong they tell to the box that evey face take all the texture (texture coordinates are zeros and ones). if anyone can help me please write to my mail vtserej@gmail.com

Look up the UVW Map modifier and the Unwrap UVW modifier. In the Unwrap UVW modifier you can use the "Flatten mapping" option to automatically assign unique texture coordinates for each polygon although that might give you texture seams in places you don't want. 3ds max 7 is ancient btw.:)
