  Here's another tweet showing the muscles in action, I'd love to know more too!

  Is this something else then a pre-"baked" blendshape-isch solution?
  So more in the direction of a realtime system driven by a muscle-like layer underneath?

  Looks like corrective blendshapes on top of skinning to me, not some live muscle simulation with skin sliding. At least for the linked Star Wars asset in Unreal that's something that is supported in engine out of the box.

  Im not sure if engines do support Pose Space Deformer.
  But im sure you can bake those into to the animation.

  The tweet kinda implies that the muscles run live in-game, but could also just say that only the pose reader is what the game runs, calling on baked blendshapes.
  
   I had already forgotten about this slick demo, he's automatically creating joints based off a blendshape, i'd imagine this could work from a muscle deformer. I've seen a similar concept recently for baking ncloth to joints.

  Looks like there was more conversation on twitter. The muscles in Maya were just there to create the blendshapes, which are called by their PSD in-game.

  Makes sense. These muscle simulations seem way too buggy to be put into a game, even if performance were not the issue.

  I still wonder how they get ZIVA muscles into a game?

  They didn't? In the twitter post he says they used Maya's muscles to create blendshapes. Though Ziva does have this.
