I’m having this trouble on rendering a metal material. The problem is there is some black lines in some parts of this model. It has a metalic material and it’s the same material applied to the screws and screwdrivers.
This problem occurs just in the render and not in viewport.
Could you provide an image of how the material you are using for these meshes is setup? Also have you tried using this material in another project and experienced the same issue?
