Curve Node

The Curve node is one of the main nodes for building a deformation rig. You can chaining Curve nodes to create a Bezier handles skeleton. The Rigging tool can be used to create and connect the nodes automatically—see About Basic Deformation Chain Creation.

Properties

Parameter

Description

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 Resting Offset

(x) Axis

This is the curve x-axis (horizontal) coordinates for the resting position.

(y) Axis

This is the curve y-axis (vertical) coordinates for the resting position.

Resting Orientation 0

This is the orientation for the first Bezier handle for the resting position.

Rest Length 0

This is the length for the first Bezier handle for the resting position.

Resting Orientation 1

This is the orientation for the second Bezier handle for the resting position.

Rest Length 1

This is the length for the second Bezier handle 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.

(x) Axis

This is the curve X-axis (horizontal) coordinates for the animation position.

(y) Axis

This is the curve Y-axis (vertical) coordinates for the animation position.

Orientation 0

This is the orientation for the first Bezier handle for the animation position.

Length 0

This is the length for the first Bezier handle for the animation position.

Orientation 1

This is the orientation for the second Bezier handle for the animation position.

Length 1

This is the length for the second Bezier handle for the animation position.

Envelope Parameters

Apply Parent Modifier's Transformation

When this option is disabled, the deformation from the parent curves are no longer affecting the current curve. Interesting effects can be achieved when disabling this effect on the last child curve and rotating the Offset point. The curve tail end will remain pinned on the spot while the rest of the curves deforms.

Close Contour

When this option is enabled, the extrimity of the curve is snapped to the initial chain's Offset point. This creates an Envelope deformation. More than one curve can be linked to the Offset point.

Region of Influence

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