When baking textures, even on a flat surface, the curvature map detects the UV seams as if they were

Thank you for your reply.

I’m not planning to use UDIMs for this model.
The reason some UVs are placed outside the main UV area is that this model is for a game and is symmetric, so this layout helps save texture space.
If I paint on the UVs inside the 0–1 area, the texture will also appear on the mirrored side.
Also, if I stack the UVs of the opposite side within the 0–1 area, it causes issues during baking.

Is there any way to stack the UVs without moving them outside the 0–1 area, while avoiding baking problems and preventing the white seam lines from appearing?
Thank you.

Hi @gotok78974243,

The example you gave here isn't a good one. You basically have overlapping UVs (considering you're not using a UDIMs workflow) with UVs out of their map.

This is a very uncommon workflow, but if you want me to take a look, you can send it at cdellenbach@adobe.com
