Specific to the Clump tool. Strength of the force that pulls hairs in the brush radius toward a centralized hair. Higher values generate tighter packed hair clumps. Clumping Intensity is affected by Falloff.

Clump Scale
Lets you control the shape of the hair clumps by setting the strength of the clump effect at different points along the length of the hairs. The base of the curve represents the center of the clump, while the left and right curve points represent the hair root and tip.
