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.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Parameter Details
Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
Scale X Scale along the local x-axis.
Scale Y Scale along the local y-axis.
Scale Z Scale along the local z-axis.
Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.
Parameter Details
Position X Toggle inheritance of the X Position from the parent.
Position Y Toggle inheritance of the Y Position from the parent.
Position Z Toggle inheritance of the Z Position from the parent.
Rotation Heading Toggle inheritance of the Rotation Heading from the parent.
Rotation Pitch Toggle inheritance of the Rotation Pitch from the parent.
Rotation Bank Toggle inheritance of the Rotation Bank from the parent.
Scale X Toggle inheritance of the X Scale from the parent.
Scale Y Toggle inheritance of the Y Scale from the parent.
Scale Z Toggle inheritance of the Z Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details
Blend Amount Global override for how much the deformer affects the mesh.
Subdivision Order Toggle whether the deformer is added before or after the object is subdivided.
- Before Subdivision : The deformation is applied before any subdivision is added.
- After Subdivision : The deformation is applied after subdivision, or inbetween if the subdivision level property is modified.
Subdivision Level The subdivision level at which the deformer is applied. Subdivision Order must be set to After Subdivision to Function.
Weightmap Add a weight map to determine where the deformer is more or less effective.
Vertex Source Mode Choose whether the deformer applies to the individual vertices or the mesh chunks.
- Vertex Positions : The mesh deformations are applied to the mesh vertices.
- Chunks : The mesh deformations are applied to the seperated mesh pieces.
Deformer Transform Space Choose which transform space the deformer uses for deformation. Does not affect falloffs.
- Local : Deformations are calculated in the Local Space of the object, so transformations of the parent mesh will not affect the deformation.
- World : Deformations are calculated in the World Space of the scene, so transformations of the parent mesh will apply the deformer differently depending on the mesh position.
Update Time Mode How the deformer updates with relation to the timecode.
- Locked To Timecode : The deformer deformations are locked to the timecode and the same time will always yield the same deformations.
- Running / Looping : The deformer deformations are disconnected from the timecode and will loop seamlessly at the end of the layer.
These properties control where the deformer affects the geometry.
Parameter Details
Falloff Enabled Enable falloff from the position of the deformer.
Falloff Shape Select which shape to use to draw falloff from.
- Sphere : How quickly the falloff drops to 0 at the outer falloff.
- Cylinder - X : Falloff is drawn radially outward from a line along the x axis, forming a cylindrical falloff.
- Cylinder - Y : Falloff is drawn radially outward from a line along the y axis, forming a cylindrical falloff.
- Cylinder - Z : Falloff is drawn radially outward from a line along the z axis, forming a cylindrical falloff.
- Plane - X : Falloff is drawn outward from a plane formed on the YZ axis.
- Plane - Y : Falloff is drawn outward from a plane formed on the XZ axis.
- Plane - Z : Falloff is drawn outward from a plane formed on the XY axis.
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 effect to no longer effective.
