It says the pony tail hair simulation is created with syflex using polygon strands. This means they modeled plenty really really thin strands to run simulation on? I'm not familiar with syflex so I wouldn't know what features it holds, but is this a good approach?
On the next one they used syflex in combination with shave and I really like the style they have there. Perhaps shave is a good way to go? But why use syflex in combination?
