Panel: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 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.
