Hair Tool is a plugin for creating animated human hair. To set it up you need a hair geometry mesh, and a few minutes to configure. Hair consist of nearly 20000 individual stands. Up to 500 of them are simulated with a physics engine, others are tesselated and interpolated.
Physics are implemented with a custom engine based on Verlet integration, and executed on GPU (Compute Shader). You can configure elasticy, gravity, and curveness in editor. Colliders can be added to bones so it interacts with body a realistically. Unity WindZone component is supported.
Lighting is based on Kajiya-Kay reflection model. You can configure color and specular facor in editor.
Shadows are implemented as a Unity shadow caster pass. Shadow receiving will be added with the next update.
Editor is Blender. 3dmax support will be added in next build.
