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 XThe objects position along the local x-axis.
Position YThe objects position along the local y-axis.
Position ZThe objects position along the local z-axis.
Rotation HeadingThe objects rotation around the local y-axis.
Rotation PitchThe objects rotation around the local x-axis.
Rotation BankThe objects rotation around the local z-axis.
Scale XThe objects scale along the local x-axis.
Scale YThe objects scale along the local y-axis.
Scale ZThe objects scale along the local z-axis.

Control the inheritance of the transforms from the parent.

ParameterDetails
PositionToggle inheritance of the Position from the parent.
RotationToggle inheritance of the Rotation from the parent.
ScaleToggle inheritance of the Scale from the parent.
World Position OnlyInherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit TimeToggle inheritance of time from the parent.

These properties control the core behaviours of the node.

ParameterDetails
Use Edge LengthDetermines whether to use the minimum edge length to select edges for subdivision.
Minimum Edge LengthThe minimum length of edges which will be subdivided.

These properties control where the deformer affects the geometry.

ParameterDetails
Use FalloffEnable falloff from the position of the deformer.
Falloff ShapeSelect which shape to use to draw falloff from.
  • Sphere : Falloff is drawn outward from a central point, forming a spherical falloff.
  • Cylinder - X/Y/Z : Falloff is drawn outward from a line, forming a cylindrical falloff.
  • Plane - X/Y/Z : Falloff is drawn outward from a plane.
Falloff RangeLimits the range the deformer is effective at.
Falloff Inner RangeThe inner range from which the falloff is calculated from.
Falloff Curve PowerHow quickly the falloff drops to 0 at the outer falloff.
Invert FalloffInvert the direction of the falloff.
Falloff CurveVisualises the falloff curve, from being completely in effect to no longer effective.
