Hello again and sorry for the late reply due summer vacation 🙂
I have attached for you here the “new” AnimatorTrack file in a .unitypackage. Please note that it is still Work in Progress.
By the way, the PlayablesAPI is indeed used in AnimatorTrack and the change I did was to indeed try to blend Animator with the Animation played in the Animator Track, but I either miss something or this is how it works, since I can’t find a way to avoid the time snap I mentioned. I hope to figure it out eventually though, if at all possible to do.
Let me know how it works for you.
(You will of course need to have an Animator Controller assigned to the Animator and have the Animator Component enabled) 🙂
