Using ARKit Mapping Evaluators

Important

Support for the Unity Live Capture package is scheduled to end as of Unity 6.1.

Field	Description
+/-	Add or remove a binding. Note that there can be more than one blendshape bound to a single ARKit input value.
Override Smoothing	Enable to override the smoothing value set by the mapper.
Smoothing	The amount of smoothing to apply to the blend shape value. It can help reduce jitter in the face capture, but it will also smooth out fast motions.
Evaluator Preset	A preset evaluation function to use. If none is assigned, a new function must be configured for this blendshape.
Type	The type of evaluation function to use when a preset is not assigned. This can be either Simple or Curve.
Multiplier	The scaling coefficient applied to the blend shape value. Larger values make the character more expressive.
Offset	Offsets the zero value of the blend shape. Non-zero values will change the face's resting pose.
Max	The maximum value of the blendshape.
Clamping	Controls how the evaluated blend shape value should behave as it reaches the maximum value. Soft clamping will ease near the max value, while hard clamping will not.

Evaluator Presets

Evaluator Presets simplify the process of applying the same evaluation parameters across many blendshape mappings.

To create a new Evaluator Preset, go to Assets > Create > Live Capture > ARKit Face Capture > Evaluator and select either Simple or Curve.

Simple Evaluator

An Evaluator that uses a mostly linear evaluation function.

Curve Evaluator

An Evaluator that uses an animation curve to define a custom function. Click the animation curve to define a curve manually or pick one from a list of presets.

The created preset asset can be applied to the Evaluator Preset field of any mapping in the Mapper.
