I see. Thanks for the reply.
I was hoping to use these UVs to create lightmaps in Unity. ( Lightmaps can't have overlaps )
Thanks, I'll find another way.
I appreciate your quick responses and updates!

I'll be adding in lightmap uvs to the next UVO for Unity update - Unfortunately I won't be able to generate lightmap UVs in the standalone program, since the code to generate them is part of the Unity Editor library.
