Hi everybody! I've got the issue with triangles showing on the model after baking high poly to low poly. I try to bake the model in Substance Painter, and in the viewport everything seems to be ok, but in Iray the triangles are visible. I found a similar issue in this topic: Triangles showing on bake/normal map and tried…
You mean shadin in Maya, right? It looks like this. As for me, I do not see problems here. If there are - please, let me know! :) P.S. I am experimenting with the edges/shells, so the meshes below are slightly different from the ones I have attached in the first message of the topic.
While the face normals (the one from a center of each triangle ) looks perfectly up those normal are derivative as a median of vertex normals in triangles corners. The bottom left corner for example , clearly not 90 degree up . it's what creates shading gradients. Face weighting, or direct normals editing could fix it .…
The shading depends on vertex normals. Flat thing should have them same directed . Typically 3d packages control vertex normal on their own but with lots of tiny long triangles errors usually happen . insetting or beveling or face weighting are just ways to help automatic algorithm. You can do same manually too. Like…
