Library of tech features used to realize the digital human from The Heretic and Enemies.

Declare the package as a git dependency in Packages/manifest.json:

-Minimum Requirements - Unity 2020.3 + - HDRP 10.9.0 +

• Requirements for Skin Deformation and Skin Attachment GPU Path

  • Unity 2021.2 +

• Requirements for new Eye and Skin Shaders

  • Unity 2022.2.0a16 +
  • HDRP 14.0.3 +

• Facial animation systems

  • Tools for 4D clip import and processing. _{(When we say 4D, we mean a sequence of meshes captured over time.)}
  • 4D clip rendering with timeline integration.
  • 4D frame fitting allowing detail injection from facial rig.
  • Integration of facial rig from Snappers.
  • Pose facial rig directly in Unity.

• Skin attachment system

  • Drive meshes and transforms in relation to dynamically deforming skin.
  • 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.
  • Custom pass for cross-material normal buffer blur (tearline).
  • Custom marker-driven occlusion for eyes and teeth.

• Added GPU path for skin deformation and skin attachment calculations.
  • When using GPU path for skin attachment target, EyeRenderer and TeethRenderer need a reference to the SkinAttachmentTarget driving the markers as the transforms aren't updated on CPU anymore
• Added skin tension to apply wrinkle maps.
• Custom pass for slight blurring around the eye lids.
• New shader graphs for eyes and skin.
• SnappersHeadRenderer now uses texture arrays. If migrating from older version of DHP, use "build texture arrays" to setup the textures properly.
