Collison Constraints Problem

[kurt-harriman]

Hi there,

I have problem to simulate accurate collisions on hair using collision spheres constraint. I read all maya help tricks, and set constraint stiffnes to lower values 0.05, also I have cache samples 4. But still when my character running, hair still going trough all of the collision spheres (I have 3 to make collision more accurate) . It collides in some places but a lot of hairs going trough collision.

Will be appreciate for any help. Thanks

have you tied decreasing simulation step size?

[kurt-harriman]

Yes, I incresed my iteration up is 16, plus I have cache over samples by 4 . Still going trough

[joojaa]

yes but that isnt very high for fast movement.
