Found this post just now.
Experienced a similar issue with nanite-enabled trees in UE 5.1.0.
If your issue is similar to what I encountered then it is not-quite-a-bug and more with how a variable that’s often used for World Position Offset changed.
Paraphrasing what worked for me here:
The workaround was to modify the
TransformPosition
’sSource
value fromLocal Space
toInstance & Particle Space
.

Good luck, I hope the info helps.
