    • Integration of facial rig from Snappers.
    • Pose facial rig directly in Unity

    • Used to drive eyebrows, eyelashes, stubble and logical markers.
    • Accelerated by C# Job System and Burst Compiler.
  • Shaders and rendering

    • Full shader graphs for skin/eyes/teeth/hair as seen in The Heretic.
