At some point I would like to make a pass through several of the file export options to add more features to them.

Since the focus for most export is for going into a rendering system, it would really be more focused on setting up material definitions, but I guess a "layer" in FBX is just a channel of some particular information that polygons can index into, like for example UV coordinates go on a particular type of layer. I don't know how Rhino's FBX importer works exactly, whether it gets its layers from one particular kind of FBX layer, there are a bunch of different layer categories, like "Material", "Vertex Color", "Visibility", "Polygon Group", "UV", etc... Do you know which particular kind of FBX layer it uses to build the Rhino layer table from?
