When looking at twitter I've found a post showing some amazing tech for facial mocap.
This tech was done by Facegood, a chinese company.

The sad news
Looks like the tool is compatible only with Maya and 3dsMax

The good news
They are making the addon for blender, I received this info on their discord server.
Tutorial:
Unfortunetely, for ocidental people like me, the best information source of tutorials to learn how to use Avatary, is their bilibili channel. I could not understand what they said, but we can learn a lot just by looking at what the guy is doing.
