Dynamic Hair stretching

[animonster]

Hello,
I have been working with some dynamic hair systems. In my most recent one, as the character lands from a high jump, the hair stretches quite a bit while rebounding. I have the "Lock Length" turned on, yet it still stretches. Can anyone help with this problem please?
Thanks,
J

Yeah. Its mainly the friction setting in the hair system. Turn it down, and do some trial and error with the itteration number. Friction can be added via the geoconnectors for collisions, but if you have it higher than 0 for the hair system, the hairs will stretch. Also, if any collision surfaces are moving through follicles, the dynamics gets messed up at they stretch out of control.

To keep the hair from stretching increase the iterations value on the hairSystem. You may also need to lower the stiffness when doing this.

Locklength is strictly for editing curves and start positions, it has nothing to do with the hair system dynamics. I would keep it OFF when not editing the start or rest curves.

The other thing you can do is increase the sampling rate for your hair cache (try 2 or 3) and also decreasing the sampling on a per follicle basis (try reducing the values from 1 to 0.7).

Hope that helps some
