Thanks Sam - I use Carrara 5, export out to LithUnwrap -because that does 3 handy things. It optimises the mesh, warns me if there's any un-triangulated bits and if I select box mapping it maps everything in one perfect square.
It doesn't muck up the material/groups names either.

Then I go into UVmapper Pro, make that full screen, then map by group/material as needed. Ticking all 3 options on box mapping. Many moons later hopefully I have some reasonable material zones that can be saved as templates. Finally once mapped spilt the vertexes.

Pinky - you left the lens cap of your mind on again.
