Well, I'm not sure if I got it, and neither if we are speaking of the same thing. Lets just clarify things. What I want to do is combine two diferent meshes. As an example: lets presume I model a body and a bull's head(thinking in one of your models

), in 3ds max, and want to join them in MM for some reason. There's no way to import them at the same time, right? But I don't want to cut a part of my model and drag it to the library to be able to then open the other mesh and combine the part with it. It would be nice if we could import things directly into the library. But I'll keep trying to understand that uv thing, and thanks for replying by the way.
Cheers.
