My model looks fine in Blender and there are no problems, however when I export it (to the Substance Painter for instance) there are artifacts all over the surface.

It could be the issue with substance, I thought about that, but something tells me that it's either normals in Blender or the export itself. The thing is that I just recently did another project and everything was fine, both in Blender and in Substance.

Btw I don't know whether it matters but I have started doing thin one on Blender 2.82 and later accidentally opened this file in Blender 3.6 (My laptop is slow that's why I prefer using the older one). Then I just kept doing it in 3.6.

At first I thought it happened due to the triangulation but when I reversed it, the issues were still there. I've tried reapplying Weighted Normals, Autosmooth and all that and I really don't know how to fix it.

  • $\begingroup$ I'm not sure about SP support of split normals, and the custom normals are definitely the problem here. Can you live with a normal map instead of custom normals? If so, you can bake object space normals and use them on a mesh without custom normals; you can bake those to tangent space normals afterwards from the obj space normals if you'd prefer, although on this mesh, obj space normals should be fine. $\endgroup$
