Grass is Patchy

[sreyes]

I am trying to figure out why my grass is coming out very patchy. I have watched numerous tutorials and I think im still missing something. My scene scale has been set in Ft from the very beginning. I also have done a "Reset XForm" prior to adding forest pack grass to the scene. My global is 100% as shown in the screen shot. Please help as I dont want patchy grass.

Also when I render with CPU it works fine. When I render in GPU Arnold Renderer. I get the following error also attached.

NVIDIA GEFORCE RTX3090
AMD RYZEN 9 5900X 12-Core

I think you need to adjust settings in "Distribution" rollout. Check the image (dense, scattered and so on) and density.
