Problem with Unity 2021 (vs Unity 2020)

[Loran75]

Hi,
Both screenshots are a scene cre ated with Gaia Pro 2021 + GeNa Pro (latest versions).
The first is Unity 2020 (HDRP), the second is Unity 2021 (HDRP).
As you can see, in the scene with Unity 2021, the grass has a kind of graininess to it.
Any idea how to fix it ?
(I have this problem with all my Gaia/Gena projects with Unity 2021)

Is the effect just limited to the grass, or does it show up elsewhere in the scene? 

 

If it affects everything, you try and see if it is a post processing issue. Select the HD Post Processing Environment Volume in the scene, and turn some of the settings on and off to see if changes the affect.

It could also be related to the anti aliasing on your camera, change these settings and see if it makes a difference:
