I tried all of the tricks that were passed around in the other forums like adding extra params around dicing and pumping up sampling and shadow resolutions with out luck.

The two params that did the trick in eliminating those nasty 2 bit square wave shadows was increasing the Shadow Quality and Shadow Softness options in the light that is casting the Depth Map Shadows.

Additionally, after testing different angles, I noticed that the edges of shadows cast from peaks were getting choppy and bumping up the Pixel Samples in the Depth Map options in the lights smoothed it all out nicely.

Feels so good to start getting traction with rendering!!

P.S. The fixed HIP is attached.

Thanks for the quick and detailed reply!

The displacement bound param fixed the missing poly problems, and I'm sure your other thread and mucking around will reveal why those square shaped shadows are appearing on such a flat surface.

This is the first time I have tried using displacement maps and am getting odd errors that mantra or lighting changes don't seem to fix.

The errors are chunky shadows and black triangular missing regions from the surface. To see what I'm seeing, look at the attached image.

It's a simple scenario, but I attached the hip file is attached as well.

I found an older post about the problem that mentioned tweaking params in mantra, but H9 removed or moved those params.

Any one else run into this problem?
