Hair Dynamics

Reference

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 insteadof the basic geometric strand model. This means constructing a regular grid such as those used influid 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.
