Are triangle groups the same as submeshes? #82

I'm trying to support mesh reduction with separate submeshes and not sure that the triangle groups are what I think they are.

triangle groups are just per-triangle integers, they don't have any inherent semantics. They are ignored by the Reducer. Not sure what you mean by a "submesh" - if you mean Unity submesh, g3Sharp does not have that concept.
