Face Tracking Deformer

Method

This node uses the vertex data from a tracked face found by the Face Tracker node to override the vertex positions of the 3D object node the deformer is attached to – if that 3D object conforms to the structure of the geometry generated by the face tracker.

This allows face tracking to be used to deform a pre-created, imported 3D object that has been designed to be used with face tracking. An example of such an object is available here.

For more information on face tracking, see the Face Tracker node.

Transform

Name Description
Position X Move its position along the x-axis in local space.
Position Y Move its position along the y-axis in local space.
Position Z Move its position along the z-axis in local space.
Rotation Heading Rotate the object about the x-axis.
Rotation Pitch Rotate the object about the y-axis.
Rotation Bank Rotate the object about the z-axis.
Scale X Scale along the x-axis.
Scale Y Scale along the y-axis.
Scale Z Scale along the z-axis.

Inherit Transform Channels

Toggle which transform channels should be inherited. By default, all are on.

Attributes

Name Description
Blend Amount How much the deformer affects the mesh.
Subdivision Order Toggle whether the deformer is added before or after the object is subdivided.
Subdivision Level The subdivision level at which the deformer is applied.
Weightmap Use a weight map to determine where the deformer is more or less effective.
Vertex Source Mode How vertexes are selected to be used by the deformer.
  • Vertex Positions, Vertexes are chosen based on their positions in the scene.
  • Chunks, Vertexes are chosen based on the enclosed section of the mesh they are used.
Deformer Transform Space Select which transform space should be used to calculate the deformations.
  • Local, Deformations are calculated in the Local Space of the object.
  • World, Deformations are calculated in the World Space of the scene.
Update Time Mode How the deformer updates with relation to the time code.
  • Locked To Timecode, The deformer deformations are locked to the time code and the same time will always yield the same deformations.
  • Running / Looping, The deformer deformations are disconnected from the time code and will loop seamlessly at the end of the layer.

Falloff

Name Description
Falloff Enabled Enable falloff from the position of the deformer.
Falloff Shape Select which shape to use to draw falloff from.
  • Sphere, Falloff is drawn outward from a central point, forming a spherical falloff.
  • Cylinder – X/Y/Z, Falloff is drawn outward from a line, forming a cylindrical falloff.
  • Plane – X/Y/Z, Falloff is drawn outward from a plane.
Falloff Range Limits the range the deformer is effective at.
Falloff Inner Range The inner range from which the falloff is calculated from.
Falloff Curve Power How quickly the falloff drops to 0 at the outer falloff.
Invert Falloff Invert the direction of the falloff.
Falloff Curve Visualises the falloff curve, from being completely in effective to not at all.
