Author Topic: Overlapping UVs in the Cage mesh - yes or no?  (Read 1742 times)

Hey everyone, I hope someone can help:)

So I know that when baking a normal map your cage must have the same UV layout that your lowpoly.
I also know that when you bake a normal map, you cannot have any overlapping UVs in your lowpoly because the bakes get added on top of each other.

My question is: Do I have to move overlapping UVs outside the 0-1 UV range for the Cage mesh as well? Or do I keep the Cage UVs overlapping?

Thanks a lot in advance!:)

Hey pacsuta.david,

I am not sure about that but I think you've answered your own question: The cage and the low poly need to have the same UVs.
If your low poly has no overlapping UVs, do the same for the cage.

Hey Fabian,

thanks for the reply. Unfortunately it turned out that my model had terrible topo for baking and the way I rebuilt it, it was no longer feasible to overlap the UVs. So right now I cannot confirm if your assumption was correct:) but if I ever come across a similar situation I'll be sure to share my findings in this post
