Hi.
I upgrade to 1.8.0f1.
I add a Skinned Model actor to SLATE, and I add Animator Track to this actor.
Animator Component is the actor’s child gameObject component, not this actor self have the component.
Then I add Animator Clip to this Animator Track, and report error:

MissingComponentException: There is no ‘Animator’ attached to the “sample” game object, but a script is trying to access it.
You probably need to add a Animator to the game object “sample”. Or your script needs to check if the component is attached before using it.

It’s work fine in 1.7.2, but 1.8 have this error report.
Thanks for your reply.
