Best way to post-edit state machine animation with Playables

Hello Animators,

I'm currently trying out the Playables API for my facial animation and liking it so far. But I am not sure on how to properly integrate it with state machine-based body animation.

So far I tried creating an AnimatorControllerPlayable for the controller containing the state machine with the humanoid body animation. Then I used AnimationLayerMixerPlayable to blend it with my face animation clip playable. The face animation layer in the AnimationLayerMixerPlayable is in additive mode, similar to how it would be if I were to use a state-machine for facial animation. The state-machine itself only contains a single layer with a single clip.

This breaks the blendshapes of the facial animation. Their weights take to extreme values that only get larger over time. The joint-based animations (body + jaw rotation from the facial animation clip) still play as normal. Since I am super new to Playables I am really not sure what is going wrong here. Any help is appreciated!

I have created a bug report for the stuff-grows-over-time bug, and it's apparently getting fixed. I got an email from @DavidGeoffroy, sharing it here since it could help you and it's not very confidential:

 

Cool, thanks for sharing.

Btw, is there any way to get notified when a bug such as this is fixed? Any web-platform where patch logs are posted or the like?

 

there is the public issue tracker

Could you please take a look at this thread? I think I have a similar problem.
I would be very grateful.
