Blocks in Render

V-Ray V-Ray GPU Issues
1

I have blocks showing up in my renders. Texture is VRScan. How do I get rid of them, never experience this before. Using VRay Next GPU, 3DSMax 2020. Motion blur and depth of field are on. Progressive sampling. RTX 2080 x 4.

I would first try disabling Adaptive Lights in the render settings. Is this one machine or distributed rendering? Block or progressive?

Are those curved modelled or is it an edgestex in bump?
If edgestex, see what happens if you switch it off
