Silly, silly UV question ....
It's been a long time since I've done any serious UV'ing, so I'm a bit embarrassed to ask, but ...
When modeling something like a camera, is it necessary to have all the UVs of every separate object in the model avoid overlapping each other even if they're separate from each other?
For instance: If the lens is a single separate object from the camera body, can its UVs encompass the entire 0-1 space or should it be scaled down so it won't overlap other objects in the scene (UVs of the camera body) even if it uses different shaders and materials?
Thanks much.
