I have an issue with smooth shading.
First I noticed it only with bump map, but then I created the attached sample scene, which shows the error even without bump.

I use v2.1 beta2.

That's the terminator problem.

Well, thanks. I see it isn't a LuxCore specific problem.
In my original scene it was caused by a hdri, therefore I couldn't increase the size of the light, so I used heavy subsurf, and it solved the issue.
