Prefab can't be transformed in editor after import from a package.

Hi everyone,

When importing a prefab with all dependencies from a package I made in a new project, it stays at the origin in the editor while its transform updates. It is simply an fbx mesh with skinned mesh renderer and animator components.

In the scene editor, Unity shows the character mesh stuck at the origin with its bouding box (see image below). Even if I disable animation import, the result is the same. It seems to be related to the skinned mesh renderer, but I couldn’t find much more information in the forum, here and inside the unity manual.

When removing this component, unity gives errors. Parenting the prefab to a gameObject won’t work either.

May anyone know how to unlock this ?
Kind regards,
Nathan

The reason is simply that you need to reset the ROOT node on the rig tab of the import settings every time you re-import.
