  • Approximately 5-10× faster guide deformation.

  • Over 5× faster long-hair generation and over 2× faster short-hair generation.

  • Over 2× faster hair clump computation.

  • Production-inspired guide deform methods that either use existing hairgen weights or compute barycentric weights for very stable and smooth interpolation.

  • Guide primitive attributes can now be types other than float. For non-float attributes, a hair will get the value of the closest guide.
