Grass not rendering properly

[Jillian]

Hello,

I love Gaia. It's such a great asset. 

I've been having an issue in Unity 2020 and 2021 where grass renders as flat white rectangles.

(Inserting an image from a URL wasn't working.)

Does anyone know what is causing this and how I can fix it?

Hi there, this is a known issue with grass in HDRP: Unity did not support grass rendering in HDRP for quite some time. We added our own grass rendering system called Flora in the Gaia Pro versions that will kick in as soon as you start the scene. So those white squares should disappear as soon as you run the scene if you have Gaia Pro.

In Unity 2021.2 they added a new grass rendering system for GPU instanced grass (Instanced Mesh mode) which you can utilize with Gaia as well, but we have not migrated our spawner configuration to use this new system yet. In the non-pro version you would need to setup Gaia to utilize an instanced mesh instead.
