Shading artifacts on the render I am trying to model Cap's Shield but when I render it, there are some artifacts near the star. Can anyone tell me what's the issue here?



Blend File
(Please your own hdri since the file would be too long)
If you decrease your Subsurf subdivisions (View and Render) down to a value of 2 this will fix the problem, I guess a high subdivision creates additional faces that try to smooth but actually mess with the topology.
