Fast Hair-to-Hair Interaction
The accurate and fast self interaction between hairs is one of the most important features of FXHair. Without proper self interaction, the hairs look unnatural and no volumetric effect of hair clumps emerges.

Goal Curves
Fast moving characters are prone to make their hairs tangled up.  FXHair provides the goal curve constraint which can control how strong the hairs are attracted to the shape of goal curves.  The strength can be scaled along a hair curve, and this scaling profile  can be set per-hair basis.  Using goal curves, you can maintain given hairstyle even under strong wind or fast movements.

Interoperability with Other Hair Tools
FXHair accepts NURBS curves as input and output. This simplicity enables users to do easy integration into existing hair tools in your pipeline. FXHair provides one-click converting function for existing Maya Hair system or Shave & Haircut node to FXHair.
