Hey there @alexmro! Welcome to the community! Judging by the shape of the artifacting, I believe that it has something to do with that banding across the sides. As clockwork mentioned, the funkiness with the noise being applied to the roughness could be at play here as well. Is there artifacting at all with a raw base color material applied?
I removed everything from the material except the basic color, I even changed the shading model from subsurface to unlit and it is still visible.
I suppose it’s the geometry. I created the object directly in UE, I wonder if I can unwrap it in such a way that it doesn’t do that or what else can I do?
Looks like the smoothing isn’t working well with non-quad geometry. It’s easier to control normal smoothing in 3rd party programs like blender, so if possible I’d recommend beginning your workflow there when doing anything that isn’t placeholder so you can have more control.
Correct! The engine is a generalized tool that can do a bit of everything, though while asset creation is slowly gaining more support, a specialized tool will always be a better option!
