Issue with Mesh Export due to extrusions (Maya, Stingray PBS, Babylon, Three.js)
02:05 20 Apr 2026

I am sort of stuck on this particular issue. I am trying to make the bottom of a capsule by taking a sphere, cutting it in half, and extruding it so it closes the shape up, then extend the top of the now half sphere to have a capsule like appearance. When I apply a Stingray PBS material with some opacity, this is what I get. I see these weird artifacts from where I extruded the sphere from and I for the life of me cannot figure out how to fix this (If I add a bevel to the edges of the lid, same issue, I don’t have the pics of that though). Any way someone can help? I can attach the main Maya file if that helps.
