It’s a simple mesh with a material but it has strange lines when looked from an angle (just using a directional light)
I tried changing the geometry (subdividing, simplifying) but it doesn’t change anything
It only happens on the sides of the cylinder. My material is this (if I try to use a normal, it’s even worse)
What should I look for?
I think it might be that stuff going into the roughness pin, have you tried removing that?
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?
Try a box unwrap. If that doesn’t do it, then it is probably the geo 
I have recreated the mesh and I realised that this happens when I click on Smooth to give it round edges
Ah… maybe it should be called bumpy, then
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.
Yes, I guess that is what I just discovered. UE is not the tool to create models; at least, very detailed ones
Yes, it’s not quite as slick as Blender yet
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!
