When i enable world position offset in any material fps drops from 60 to 12. How to fix this. Thinking it’s something due to lumen work…

More likely Nanite. It doesn’t work with WPO.

Nanite is disabled for this exact mesh. Thus it turns out that i can’t create foliage with wind…

It is invalidating the shadow cache pages first cvar is a fix for that, if you are doing anything with camera FOV see the last cvar

r.Shadow.Virtual.Cache.MaxMaterialPositionInvalidationRange 10
aaand after 2 sleepless nights
r.Shadow.Virtual.NonNanite.IncludeInCoarsePages 0 (if you have alot of non nanite stuff casting shadows)

Zooming a Camera causes shadowdepths to increase beyond reason - Unreal Engine / Rendering - Unreal Engine Forums
