Set Material Deformer

Set Material Deformer

Updated: 3 Feb 2025

Assigns a material to polygons of the parent mesh
Example .dfx

Method #

This node allows an input material to be assigned to selected polygons of the parent mesh. Weight maps and the falloff parameters may be used to control the selection.

This node simply swaps the material ID for the affected surfaces, so blending effects aren possible. For more complex effects, check out the Blend Materials node.

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
Apply ModeChoose whether the deformer applies to the individual vertices or the mesh chunks.
  • Vertex Positions : ERROR: Variable not found: {att-node-deformers-vertex-source-mode-vertex-positions}
  • Chunks : ERROR: Variable not found: {att-node-deformers-vertex-source-mode-mesh-chunks}

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.
