No Grass in Objects has been updated, you can now generate grass pre-cache for all versions of Skyrim (including VR):
https://www.nexusmods.com/skyrimspecialedition/mods/42161
------------------------------------------------------------------------------------------------------------------------------------------------------------
This mod is for advanced users who are familiar with using xLODGen, TexGen, & DynDOLOD.
The use case is if you want grass LOD, but can't run No Grass in Objects for whatever reason, or you just don't want to generate it yourself.
This grass cache was generated with only Northern Grass SE and Skyrim Landscape and Water Fixes enabled. This means that if you have mods that add things to, and/or change the landscape, there will issues, like floating grass.
Installation:
ModOrganizer: Install as any other mod. It will complain that "The content of <data> does not look valid", ignore that, and click "Ignore" on the next pop-up as well.
Vortex: No idea, sorry.
Once installed you will then run xLOD, TexGen, and DynDOLOD.
