Hello everyone,
I’m currently testing out the grass output node for a terrain material.
From what I can see, the cluster culling depends directly on the section size of your terrain. So if you have big values for your terrain’s section size, no culling might occur.
So if you have like 127x127 section size terrain, try to change it to 7x7, and see whether that works for you!Bear in mind that getting smaller section sizes will add more cost to your CPU, since you are adding more LODs!
EDIT: The stuff above only applies if there is at least one material applied to the grass you want to instance, with the Dithered LOD bool set to false. Turning it to true solved the problem!
