Unity offers free Digital Human project with 3D character including facial animation, this project is mainly for learning purpose so it is has a restricted license you can use only for the non-commercial purpose
How to setup Digital Human 3D character in unity
While working on the realistic digital human in The Heretic, the Demo Team needed to set up a complete data pipeline, from the acquisition of 3D and 4D data through processing and into the setup in Unity. unity developed some technologies to enable this. While a lot more work remains to be done in the future, we’re sharing what unity have today, so that you can look into the current state of our efforts. You’re free to use these tools in your productions and build on top of them as you see fit.
Here’s what’s included in the project :
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 detailed injection from the 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 (tear line) and marker-driven occlusion for eyes and teeth.
unity also releasing the character Gawain, a digital character modeled after British actor Jake Fairbrother. We are making this 3D character available to you for the purpose of learning, research, and similar non-commercial use intended for the advancement and sharing of knowledge in the space of real-time graphics and content creation.
