Subdivider

Summary

The Subdivider divides, extrudes, and rotates polygon faces based on a Falloff Attribute, if enabled. A falloff value of 1.0 means that the corresponding primitive will subdivide and extrude exactly the number of times specified by the Max Subdivisions parameter. The Extrude Strength defines the peak extrusion distance, while the Falloff Exponent controls the gradual falloff of extrusion between iterations. The Inset parameter further affects the shape of each subdivided region, allowing additional control over the local geometry structure and depth.
