Hi everyone! I'm trying to convert a .blend model to VRChat, but I've run into a critical error in the Unity SDK.
The Error: "Transform hierarchy resides in a Prefab asset and cannot be set to prevent data corruption."
What I've tried: I imported the .blend file and set the rig to Humanoid, but the SDK won't let me proceed because of these transform issues.
I'm using a model from a third-party site (can't link it here due to filters, but it's a standard base).
Does anyone know how to fix this hierarchy error? Do I need to "Unpack Prefab" or is there something I should change in Blender before exporting?
Thanks in advance for any advice!

Many of the bones aren't even attached to the model. Is it better to start from scratch with this model? The author's model has over 100 bones.
