JoeAlter Shave and A Haircut v4.5v25 for Maya (Windows/Linux)

This is the finest and fastest photo-realistic hair renderer money can buy, and has more in common with ILM's Oscar-winning hair renderer than it has with its competitors. This altogether new fractal hair rendering algorithm requires less than 32MB of RAM to render millions of hairs, and is several orders of magnitude faster than previous approaches. Shave And A Haircut comes with hair modeling tools that have no equal. In addition to automatic grooming, guide hairs are incredibly fast bi-directional IK chains. You can control them one at a time, or grab thousands and just comb away. There is collision detection built into the sculpting process as well, so hair goes around the skull, not through it.
