artifacts on the curvature map

stoparik

Hello

When baking a curvature map, artifacts appear

Something similar to polygons

This happens both when baking from a mesh and when generating from a normal map

I bake it in  substance painter

Does anyone know how to fix this? Thank you!

Hi! What does the highpoly shading look like?
Ideally share the meshes, so people can reproduce the issue.

Hi! You might want to look at the Curvature Map parameters of the baker. Increasing the sampling radius and adjusting the tone mapping might help. Other than that could also check out if AO or thickness maps are any use to build a mask.

This is literally curvature of the surface, so it does show you the polygons. In case of subdiv HP models, I prefer to increase iterations up to 3 to bump up an overall amount of polys. In case of sculpted stuff either play with the sampling radius or decimate less if using decimation master in ZBrush.
