Strange mirror uv problem in painter.

segawon · May 24 2025

So, i came across this problem yesterday. Somehow mirrored uv showing weird shading only on curved surface to x axis. No sharp edges, flipped normal, overlap vertex etc. Everything was correct, the onlything i know is its from the normal map i baked in marmoset.

2nd picture, for a completely flat surface everything is fine. but in the circle hole is not. it was one whole mesh. anyone experience this issue before?

Is that on the UV seam? Are you loading the tangent space with the incoming model, or recomputing it? https://helpx.adobe.com/substance-3d-bake/features/tangent-space.html
