Method #
This node iteratively and randomly replaces selected polygons of the parent mesh with extruded shapes. Weight maps and the falloff parameters may be used to control the selection. This node generates a large number of polygons for each input polygon, so care should be taken when using high polygon source meshes.
Parameters
Parameter Details Subdivision Order Toggle whether the deformer is added before or after the object is subdivided.
Subdivision Level The subdivision level at which the deformer is applied. Subdivision Order must be set to After Subdivision to Function.
Polygon Contraction Controls how much the extruded shapes are contracted from the source polygons.
Offset By Normal Controls the amount of extrusion, in the direction of the polygon normal.
Seed The random seed.
Minimum Polygon Area The area below which polygons will not be extruded.
Num Iterations The number of extrusion iterations. increasing the number of iterations will greatly increase the number of polygons generated.
Parameter Details Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
Scale X Scale along the local x-axis.
Scale Y Scale along the local y-axis.
Scale Z Scale along the local z-axis.
Control the inheritance of the transforms from the parent.
Parameter Details Falloff Enabled Enable falloff from the position of the deformer.
Falloff Shape Select 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 Range Limits the range the deformer is effective at.
Falloff Inner Range The inner range from which the falloff is calculated from.
Falloff Curve Power How quickly the falloff drops to 0 at the outer falloff.
Invert Falloff Invert the direction of the falloff.
Falloff Curve Visualises the falloff curve, from being completely in effect to no longer effective.
