Subdivide

Subdivide

Updated: 3 Feb 2025

Iteratively subdivides the polygons of the parent mesh
Example .dfx

Method #

This node subdivides the geometry of the parent mesh. It splits every edge in half and adds a centre vertex to each, then adds a new centre vertex to each polygon; this turns every triangle into three quads, and every quad into four quads. Subdivision can be variable: edges and polygons can be selected for subdivision using a minimum edge length threshold, or via falloff controls and weight maps.

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.

ParameterDetails
Position X The objects position along the local x-axis.
Position Y The objects position along the local y-axis.
Position Z The objects position along the local z-axis.
Rotation Heading The objects rotation around the local y-axis.
Rotation Pitch The objects rotation around the local x-axis.
Rotation Bank The objects rotation around the local z-axis.
Scale X The objects scale along the local x-axis.
Scale Y The objects scale along the local y-axis.
Scale Z The objects scale along the local z-axis.

Control the inheritance of the transforms from the parent.

ParameterDetails
Position Toggle inheritance of the Position from the parent.
Rotation Toggle inheritance of the Rotation from the parent.
Scale Toggle inheritance of the 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.

ParameterDetails
Iterations How many times to divide the polygon.
Use Edge Length Determines whether to use the minimum edge length to select edges for subdivision.
Minimum Edge Length The minimum length of edges which will be subdivided.
Smoothing Smoothing algorithm.
Weightmap Mode Set how the weightmap is used to apply subdivision iterations.
  • Iterations : Sets the iteration value linearly based on the weightmap value.
  • Values Thresholded : Allows you to set a weightmap value threshold above which the subdivision will be applied.
  • Differences : Subdivides more where there is more change in the weightmap value.
Weightmap Threshold Sets the threshold point of the weightmap when using “Values Thresholded” or “Differences” weightmap modes.

These properties control where the deformer affects the geometry.

ParameterDetails
Enabled Enable falloff from the position of the deformer.
Shape Select which shape to use to draw falloff from.
  • Sphere : Falloff is drawn outward from a central point, forming a spherical falloff.
  • Cylinder : Falloff is drawn outward from a line, forming a cylindrical falloff.
  • Plane : Falloff is drawn outward from a plane.
Shape Orientation Along which axis the shape should be drawn.
Outer Range The outer range from which the falloff is calculated from.
Inner Range The inner range from which the falloff is calculated from.
Curve Power How quickly the falloff drops to 0 at the outer falloff.
