I've been using Blender a lot and I have a commission due to this weekend.

I sculpted a mesh and then retopologyzed it, baked the Normal Map from the Highres to lowres mesh with "Selected to Active" as i've always did.

The problem is, when I lower the camera with Cycles, it will show black artifact on the mesh.Decimated and Retopo'ed

On the left, there is a mesh that I decimated and on the right the retopology. Original mesh

This one is the original mesh, I tried to test the same normal map on the original mesh and the same issue occurs.

I've also tried to open a new file, sculpt on a UV Sphere, then baked the normal. The issue is still there.Ball

With this ball I just baked the normal without "Selected to active"

What's the issue here? I thought it was a topology related issue but it happens on normal quad meshes too.

I am on version: 3.2.2, branch: master, commit date: 2022-08-02 18:15, hash: bcfdb14560e7, type: release build date: 2022-08-02, 23:41:46

Edit, I've also tried on 2.93. Same issue occurs

  • $\begingroup$ Can you share the sphere file? It can be wrong normal setup, duplicated geometry or maybe something reflects? $\endgroup$

Color space should be non-color, and normal map node should be used to convert tangent normal map to object space normals:
