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