Method
This node defines a spline in 3D space from a number of control points. Control points are specified by linking Null nodes to the Spline Nodes input. The position of each Null is used as the position of the control point; the rotation of the Null is used to control the tangent direction of the spline at the control point. The ordering of the control points is defined by the vertical ordering of the nodes.
Splines may also be imported from 3D packages as part of Imported 3D Scenes.
Splines may be used in conjunction with Spline Followers to allow geometry or transforms to follow the path of a spline. Splines may also be used with Particle Spline Emitters to emit particles from splines, Spline Deformers to deform 3D objects using splines, and numerous other uses.
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 y-axis. |
| Rotation Pitch | Rotate the object about the x-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.

Outputs
This node outputs a spline which can be used to as an input into other nodes which use splines to generate new effects.
