[Bf-committers] Active layers in render (logical error)

[Campbell Barton]

Blender has a logical error in UVlayers at the moment.
The TexFace material option only renders active UVLayer and Bake only 
bakes to the active UVLayer.

so if you want to bake from one layer to another, you cant (you can if 
you make the image a texture, and remove texface option but thats not ideal)

We need a way for texface to set a layer name, or a way to set the 
"Render Layer" for VCols and UVLayers

Both have advantages and disadvantages..

* Using the layer name, means every mesh that has that material but use 
the name set in the material.

* Having a "render layer" means every material will have to render the 
same layer (could couldnt have 2 materials on the 1 mesh each 
referencing their own UV layer)

Briggs suggested we have a texface texture type so texface's can be 
stacked... not sure how that could fit in.
