```

### Parameters

**** (\[GameObject]\(/engine/6000.6/script-reference/unityengine/gameobject)):

This lets you change each root transform hierarchy before other artifacts are imported, such as the avatar or animation clips. If this function destroys the root hierarchy, any associated animation clips are not imported.
