Hair self collisions vellum

Recommended Posts


I need to sim groom that needs to be quite stiff, but hair should self collide and layers should stay on top of each other. I can`t seem to make it work.

Here`s simple example scene that I`m working on to test it. Any tips of how to make it work are welcome :)

So the biggest offender was checkbox in vellum constraints node, that was computing missing orientation.

Unchecked that and played around with pscale, to stop them from intersecting at first frame. Substeps, collision passes. and got it to somewhat work.

Only when some hair is intersecting can`t increase pscale to make it stack more on top of each other. maybe I will try layer shock. 

Not sure how that would work on hair?
