Avatar Authoring - Facial Morph Targets
How to set up Facial Morph Targets for your avatar.
These morph targets are used by ARKit and Webcam for Face Tracking.
Model Requirements
kemorig uses the standard 52 "ARKit" shapes for face tracking. Webcam tracking, while not actually ARKit, uses a subset of the same morph targets.
Your model must implement morph targets (aka blendshapes or shapekeys).
kemorig uses the standard 52 “ARKit” morph targets. See the following list: (NOTE: these are the exact case sensitive names kemorig uses):
You can find various references online for how to author these. Here are a few:
- Apple’s ARKit Documentation (official docs, but spread across multiple pages)
- arkit-face-blendshapes.com
- “Get your model ready for Perfect-Sync”
Morph Target Naming Convention
Your model’s morph targets do not have to match the exact names above. However, it is good practice to name closely to the list, which will help auto-detction find your morph targets.
Do I Need All 52?
No. Any missing morph targets will simply not play, and the rest will work.
In the mapping asset we’ll make below, you can also map one of your model’s morph target to multiple expected ARKit names.
Obviously, if you don’t implement all 52, the final look may suffer.
Webcam Morph Target subset
Webcam Tracking uses a subset of the full list above.
For Webcam tracking, you can choose to set up all morph targets, or just the following subset. Whatever morph targets the tracking finds, it will apply:
