stwert - I just wanted to know what might be a good way to work on a project in a structured manner and wasn't sure if it would be more efficient to do all the UVing at the same time or straight after modelling each of the objects in the scene. I think if I did UV everything after all the modelling was done, I would go a little mad

Daverave - I take it the same is also true for a layered tiff? How well does it read the layer blending modes and various layer effects? I guess that is only of benefit when your still editing your texture.
