Short description of error
Baked normal map contains artifacts when baking from High-poly geometry with Bevel shader applied. Artifacts seem to be based on High-poly topology, changing it's triangulation affects the result, but does not eliminate artifacts completely.
Rendering just High-poly object with Bevel shader applied does not display similar artifacts on its own. Baking normal map using same objects without applying Bevel shader does not display these artifacts either.
Exact steps for others to reproduce the error
With attached .blend file click "Bake" on the right side of the UI. Observe resulting normal map artifacts.
