Strange artifact on Geometry
Some kind of bug
 
Attached an image showing the thing. It´s a continuous floor that curves up . I have tried both Meshsmooth and Turbosmooth bit its the same problem. as if I had different smoothing groups in the object. See image and a stripped down 2018-max-file.

Seems to be a problem when it´s lit by the environment map. If I turn it of and only use centileo lights the artifact goes away.

Hi Daniel, thanks for bugreport. I will download and see what is going on there.

Btw, I am still fighting with displacement mapping. There was a need to imrpove render times after memory optimisation. Solving it is almost ready. Hope that problems go away.

I have detected the issue. And strange thing it goes away when reduce Diffuse roughness or change Reflection roughness, IOR. Will dig, there is something with material evaluation.
 
Thanks! And looking forward to your next release!

Yesterday I have won a battle for rendering speed of compressed displacement. The approach was based on pre-tesselation like Arnold, Redshift (not like Octane) because we need to support any kind of combinations of shaders and uv. It was all good, but after all adaptive polygon reductions the poly counts for high quality were still pretty high. And then all of this data was compressed very much. However, render speed dropped 30-50% compared to non-compression. For some weeks there were many attempts to fix that and it's fixed now! No speed lost :) Now it tesselates quickly, memory is very efficient and renders fast. Now need to fix small things, and this can be done much quicker.

The issue is fixed in 0.55!
