Wow thanks for the speedy reply but i would imagine allot of texture loss in anything smaller than 512 another question.
When mapping in my uv editor can i have uv's overlapping each other to share texture's, and i mean :
lets say i have a small building for example and it has :
and a door
can i have the two window uv's on top of each other and have the 3 wall's do the same?
I am aiming at the unity 3d engine would this be a problem for for mobile's ?
also what could you tell me about light mapping what sizes should i keep those ? or do you suppose it would be best to just bake the shadow's in my 3d package.
