HairClump is a Blender add-on designed to parametrically control the randomness of hair particle shapes. It uses virtual parents to customize clump counts and seeds, offering multiple randomization controls for length, curve, shape, and noise. The add-on includes specialized modes for curl, radial, wave, and braid deformations with adjustable amplitudes and frequencies.

Additionally, it provides a one-click Alembic export feature for particles and instances, streamlining the transition of complex hair styles and grooms into other applications or pipeline stages.
