How to eliminate environment map artifacts

[gkjohnson]

Assuming this is just a normal render with no postprocessing (an example would be helpful) it looks like geometric specular aliasing due to small triangles. This post discusses it a bit:

Having Geometric Specular Antialiasing would be incredible

Hello! How’s going? I’m working on a offsceen canvas model visualizer for fine art prints that we make in our creative studio. It’s a PBR workflow and so far, it looks really good. However, at certain angles, the aluminum material from the back of the object will cause a lot of specular aliasing on it. It was a lot worse before because the front face of the aluminum object (just behind the artwork plane) would be lit by the environment map, so I had to set a black 1.0 roughness material to it.…
