Black Wolf
It keeps falling down my list of things to do.
Currently the model has 2 uv sets. One for layout the other for final bake. The final uv map is dividable by two. eg a 4096x2048 can be turned into 2x 2048 maps without much trouble. The reason for the two uv sets was to allow different versions to be created easily.


Layout UV. The image gets filled with suitable textures.

Bake UV. This is the final uv map. It works with AO maps and also with normal maps created in PS/Gimp

It is in Blend format. I haven't looked into a way to export the model and retain the two uv sets.
