When using automotive materials. I am confronting this problem. There is a black mesh surface like artifact appearing in the defult placing angle of the object. when i turn the angle around, the artifacts go away. I tried to fix this by re unwrapping the UV or changing the material parameters in the instance, but I can’t fix this, does anybody know about this problem?
On the Automotive Materials, if you look at the material instance, go to the UV parameters section. There is one for Tri Planar Rotation. Adjusting the value from the default, to say 0.05 solves this problem.
