Spline Extend

Updated: 3 Feb 2025

Cut and extend a parent mesh along a spline

Example .dfx

Method #

This node cuts the parent mesh along the chosen axis, extends the cut faces with subdivisions, and fits the result on to a spline. The spline time values can be modified to determine which part of the spline should be used. This node requires a node that provides a spline be connected to the Spline input. Nodes that provide a spline include Spline and Editable Spline nodes, and geometry nodes which have been converted to splines. If the source provides multiple splines, the extended geometry will be duplicated to each spline.

Parameters

Attributes

These properties control the core behaviours of the node.

Parameter	Details
Cut Axis	The axis to perform the cut.
Cut Offset	The offset along the cut axis at which to perform the cut.
Subdivisions	The number of subdivisions of each extended cut face.
Match Spline Subdivision	Controls how the subdivisions generated on the surface react to changes in the spline time min/max. When disabled, the number of subdivisions (and thus the number of resultant polygons) remains constant, and move along with Spline Min/Max. When enabled, the subdivisions are static along the spline, and dynamically generate along the spline when needed.
Spline Time Min	The minimum of the used spline range, between 0 and 1.
Spline Time Max	The maximum of the used spline range, between 0 and 1.

Inputs

Name	Description	Typical Input
Spline	The source spline.	Spline
Extend Material	The material to use for the extended mesh.	Material
Generated Weightmap	Add a weightmap to vary the strength of the deformer across the surface.	Generate Weightmap
Transform Modifiers	Apply the transforms of another node to this node.	Null
Target Node	Modifiy the rotations of the node to always direct the z axis towards the input.	Null
Local Transform Override	Apply the transforms of another node to this node, relative to its parent.	Null
