When I’m doing my LookDev in Maya, I plug in my albedo maps to subsurface scattering and when I render, my mesh has these weird line artifacts going. I don’t know what’s causing it. I’ve tried using three different projects and I still get the same result, in both Arnold and Vray. But when I turn up the diffuse amount the lines go away. I have no idea why this is happening.
I assume your mesh is comming from Zbrush and is not welded together.
Select one of those face groups and move them to check if they are welded.
