What would be a good Material Type for Hair? Or does anyone have a material they could upload to KeyShot cloud??
Use metal... that's a good start
hair greatly depends on how it's modeled.
hair is definitely anisotropic.
The most common cheat used is to render with "hair cards" in which you have a card with several strands of hair on it, layered on top of eachother. You can look this up on your iceage dvd/bluray extras. They illustrate it well there, and it shows how long people have been doing it.
A newer way is to actually grow strands of hair with curves. These are usually only meshed at render time and hidden parts won't mesh. There are a bunch of cheats. Also, since they are so thin, you usually need some special allowances for antialiasing.
So in short. I'd probably start with anisotropic, but it really depends on your scale, and what kind of hair you're after. Hair will have to be completely modeled in Keyshot. They don't currently have a hair growth tool.
There is a hair material coming in KeyShot 6.x (probably not in 6.0 though)
Anisotropic doesn't work very well... seen it, pinched it, spent it.
Metal works really well in conjunction with curvature
