Package: com.unity.demoteam.digital-human

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

Usage

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

    ...
}

-Minimum Requirements

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.
