UOculusXRFaceTrackingComponent Class
Extends
UActorComponent
Fields
FName
TargetMeshComponentName
[Get]
The name of the skinned mesh component that this component targets for facial expression. This must be the name of a component on this actor.
float
InvalidFaceDataResetTime
[Get]
If the face data is invalid for at least this or longer than this time then all face blendshapes/morph targets are reset to zero.
TMap<
EOculusXRFaceExpression
, FName >
ExpressionNames
[Get]
The list of expressions that this component supports. Names are validated on startup so only valid morph targets on the skeletal mesh will be targeted.
TArray<
FOculusXRFaceExpressionModifier
>
ExpressionModifiers
[Get]
An array of optional expression modifiers that can be applied.
bool
bUpdateFace
[Get]
This flag determines if the face should be updated or not during the components tick.
bool
bUseModifiers
[Get]
This flag determines if the face should be modified with Expression Modifiers or not during the components tick.
