Hey, thanks for this! Below is the parent material. I couldn’t find the TransformPosition node unfortunately.
So I opened up MF_AdvancedWind and was confronted with this… 
But couldn’t find it in there either. I then tried looking inside MF_SimpleWind but nothing. These megascans trees are seemingly made differently. I’d have no idea where to look for the right setting. Any further ideas?
As it’s only the foliage instances having this issue and not the static meshes I’d be surprised it’s a material thing. Was your case identical in this regard? Or did your problem also exist on static meshes placed directly into the scene without use of foliage mode? Cheers
