Object Position error when Mesh is in Prefab

Hi everyone,

I have a very strange problem with a foliage Shader Graph based on this example:

I’m using it in a URP project with a mesh that has 3 LODs. This works perfectly fine in the editor as well as in-game. However, when I create a Prefab from the meshes, it goes absolutely crazy. Essentially the mesh’s vertices in sync with the animation of the foliage get stretched towards a point off screen and then come back. I’ve tested this with multiple versions of unity including the latest and it happens everywhere.

Here’s where it gets even weirder: if I unpack the preset, the problem remains. However, if I add the meshes into the scene from scratch it doesn’t. If I then turn the game object into a Prefab again, it starts happening.

I’m at a loss and would appreciate any pointers you might have for me. Thank you I’m advance!

Did you figure this out? I’m having the same issue with humanoid meshes
