Hi Michael,

Sorry for the little delay, I had to think about it, but I would say your solid based idea probably fit the best 'my' workflow.
Probably because I don't use style at an exteme condition, I often make all my material attribution in an other software.

As far as every uv islands have the same ratio (so no stretching/scale difference between every uv's island).

Still have to think about it a little bit too :)
