Combine by mesh and combine by entity produces overlapping UVs #6

Hey!

I've found when trying to bake lighting on the maps unity warns of overlapping UVs Heres an example https://imgur.com/a/UgP9hoZ

You can see the lighting doesnt get applied properly because another part of the mesh is overlapping on the UVs

Found a work around by exporting the mesh in unity using this package https://assetstore.unity.com/packages/essentials/fbx-exporter-101408 then within unity clicking the "Generate Lightmap UVs" in the model import, all of the textures seem to still look correct, and the lightmaps now bake nicely

Well, I'm not sure what exactly this means or how to fix it, but I'll look into it. It's a very strange error.

This means you need to generate uv2 for lightmaps.
