If you’re finding the default 3ds Max hair/fur somewhat limiting, you might want to check out Hair Farm by Cyber Radiance.
Quote from the website:
Hair Farm was designed and developed by Cem Yuksel, a Computer Graphics researcher at Texas A&M University, over the course of more than 6 years.
When Cem Yuksel first started the Hair Farm project, the available technologies in Computer Graphics for modeling, animating, and rendering hair were very limited and under-developed for producing a hair software that would fully satisfy an artist. Therefore, while he was writing Hair Farm, he also got engaged in a number of research activities and proposed various novel technologies required for a solid hair modeling, animation, and rendering software.
Hair Farm is not just another tool for producing hair on virtual characters. It is a completely new design that combines state-of-the-art technologies with an artist-friendly user interface and a flexible workflow.
