Well heres the thing… destination lightmap index doesnt even exist as an option modify. I remember that option so i was looking for it and its not there at all. My UV zero has its own chunks already, but i didnt want to have to create another uv set by hand or even duplicate the uv set inside my 3d package. Right now… its just simply not creating UV channel 1… and i dont ahve an option for destination lightmap index …
