Are lightmaps per FBX file or per object within it?

Unity Engine

Hi,

I was wondering how Unity bakes its lightmaps. So I import 1 FBX file that contains say 3 separate objects (not combined within Maya, can be selected individually) and each object has a second UV channel with the lightmap UVs. I then build lighting. Does Unity read each object as a separate lightmap or each FBX as a separate lightmap? Will the 3 objects have overlapping lightmap UVs?

Maybe this is obvious but I’m not too sure!
Thanks
Sarah

Don’t worry. Their UV won’t overlap.
It’s count as normal individual object each within grouping.
So simply answer your question. The answer is : Per object.:slight_smile:
