Audio Driven Animation, retarget.

I’m not using Metahuman, as it doesn’t fit my project, but the characters I created have the 52 shapes from Arkit.

I did try Audio Driven Animation, which converts audio dialogue into facial animation, and I succeeded without any problems using Metahuman.

I’d like to know if it’s possible to create a bridge between the two? Or perhaps use this functionality directly for my characters. I’ve also created a complete rig for the face.
