Bone Node

The Bone node is one of the main nodes used to build a deformation rig. Each Bone node consists of a bone and an articulation. You can chain Bone nodes to create a skeleton chain for your character. The Rigging tool can be used to create and connect those nodes automatically—see About Basic Deformation Chain Creation.

Properties

Parameter Descriptions
Enable/Disable

Enables or disables the selected node in the Camera, Timeline, and Node views.

Colour Swatch

Changes the node and layer colour.

Name Use this field to rename the node.
Resting Parameters Rest Offset
(x) Axis This is the bone x-axis (horizontal) coordinates for the resting position.
(y) Axis This is the bone y-axis (vertical) coordinates for the resting position.
Rest Radius This is the articulation's radius value (articulation size) for the resting position.
Rest Orientation This is the bone's orientation angle for the resting position.
Rest Bias This is the articulation's bias (roundness and smoothness) for the resting position.
Rest Length This is the bone's length for the resting position.
Deform Parameters Offset
2D Path When this option is enabled, the X and Y-axis parameters are controlled by the same 2D path function.
Separate When this option is enabled, the X and Y-axis parameters are individual one from another.
Path When using a 2D Path, this field displays the name of the function.
(x) Axis This is the bone X-axis (horizontal) coordinates for the animation position. This parameter can be linked to a function to be animated over time.
(y) Axis This is the bone y-axis (vertical) coordinates for the animation position. This parameter can be linked to a function to be animated over time.
Radius This is the articulation's radius value (articulation size) for the animation position. This parameter can be linked to a function to be animated over time.
Orientation This is the bone's orientation angle for the animation position. This parameter can be linked to a function to be animated over time.
Bias This is the articulation's bias (roundness and smoothness) for the animation position. This parameter can be linked to a function to be animated over time.
Length This is the bone's length for the animation position. This parameter can be linked to a function to be animated over time.

Region of Influence

Influence Fade Radius This defines the size of the fade area around the actual region of influence's boundaries—see Bone Node.
Transversal Influence Radius Left

When the Symmetric Ellipse of Influence option is enabled, this field controls the Left and Right transversal radius values. When disabled, it controls the size of the left transversal radius. By default, this value is set to 2.

Transversal Influence Radius Right

When the Symmetric Ellipse of Influence option is enabled, this field becomes inactive. The Left Transversal radius value is automatically applied to the Right Transversal. When the Symmetric Ellipse of Influence option is disabled, it controls the size of the Right Transversal radius. By default, this value is set to 2.

Longitudinal Influence Radius Begin

When the Symmetric Ellipse of Influence option is enabled, this field becomes inactive. The End Longitudinal value is automatically applied to the Begin Longitudinal value. When the Symmetric Ellipse of Influence option is disabled, it controls the size of the Begin Longitudinal radius. By default, this value is set to 0.25.

Longitudinal Influence Radius End

When the Symmetric Ellipse of Influence option is enabled, this field controls both the Begin and End Longitudinal radius values. When this option is disabled, it controls the size of the End Longitudinal radius. By default, this value is set to 0.25.

Symmetric Ellipse Influence

Enabled by default. The shape of the ellipse will be symmetrical on both the transversal and longitudinal radii. In this case, use the Transversal Influence Radius Left field to set the transversal radius value and use the Longitudinal Influence Radius End field to set the longitudinal radius value. The two other fields will remain unused unless you disable the Symmetric Ellipse Influence option. In that case, you can set up different radius sizes for the four radii directions.
