Regression

Yes

"Animator.GetBoneTransform" doesn't get bone's transform from prefab

Animation

-

Reproduction steps:
1. Open attached project "Dellt.zip" and scene "Addon"
2. Enter Play Mode
3. Observe Console window

Expected result: No errors
Actual result: "NullReferenceException: Object reference not set to an instance of an object MecanimToRagdoll.GetBone" error

Reproducible with: 2020.2.2f1, 2020.3.5f1, 2021.1.4f1, 2021.2.0a14
Not reproducible with: 2019.4.24f1, 2020.2.1f1
Could not test with: 2018.4.34f1 (compilation errors break project)

  1. Resolution Note:

    GetBoneTransform requires an active animator to return the correct transform.
    Prefabs don't have active animators until they are instantiated.
    The best way to fix the sample in this case would be to instantiate the prefabs in the Start method, cache the poses from the prefabs for later use, and remove the instantiated prefabs.
