Particle System ‣ Hair Dynamics

Hair particles can have dynamic properties using physics. To enable hair physics, click the checkbox beside Hair Dynamics.

Options

Structure

Mass

Value for the mass of the hair.

Stiffness

Controls the bending stiffness of the hair strands.

Random

Random stiffness of hair.

Damping

Damping of bending motion.

Volume

Some phenomena of real-world hair can be simulated more efficiently using a volumetric model instead of the basic geometric strand model. This means constructing a regular grid such as those used in fluid simulations and interpolating hair properties between the grid cells.

Air Drag

Controls how thick the air is around the hair causing the hair to flow slower.

Internal Friction

Amount of friction between individual hairs.

Density Target

Maximum density if the hair.

Strength

The influence that the Density Target has on the simulation.

Voxel Grid Cell Size

Size of the voxel grid cells for interaction effects.

Pinning

Goal Strength

Spring stiffness of the vertex target position.

Quality

Steps

Quality of the simulation in steps per frame. (higher is better quality but slower).

Hair Grid

Show hair simulation grid.

Warning

If you use motion blur in your animation, you will need to bake one extra frame past the last frame which you will be rendering.
