Is there a way to solve terminator artifacts?

Question

Has anyone found a way to fix the problem? Increasing the subdivisions the artifacts remains, less visible because the polygons are smaller. I have also attached Arnold image (Redshift is very similar) even with less subdivisions and more contrast that work better.

It does not seem the same problem. I used a simple cube with the subdivision modifier. I've read that it is a known problem, in Mental Ray was resolved many years ago, Renderman may still have this problem. I would like to see if there is a way to fix it in the latest version of Blender 2.79. — Riccardo, Oct 19 '17 at 20:26

From blender 2.90, you can tweak this using the Object's Shadow Terminator Offset Shading property.

Terminator artifacts are a complicated topic of raytracing. From a technical point of view the normal of the face shows the way from the light source. Therefore the face is not illuminated by light and a shadow is cast at the right place. Even if it is technically expected behavior and does not mean a "bug" - from the user's point of view this is often not the desired effect of smooth shading.

Simple measures to work around the problem are:

More geometry through subdevision
or create the normals with a high resolution mesh and back to the low res mesh
large area lighting

Some render engines work around this problem in different ways. Requests for solution of this problem are in the bugtracker for a while now. current information can be found here.
