Dforce Settings

Masterstroke

I recently have managed to convert a transmapped polygon hair into a polygon dforce hair.
The simulation is stable, without explosions and no hair is falling off the scalp.
Great, but:
During simulation the single hair cards are collapsing into some kind of spaghetti, making the hair thin and almost looking wet.
Is there any setting, that prevent that from happening?

You can try to increase Buckling Stiffness and reduce Buckling Ratio. That will make the hair more rigid.

Or load one of Lindays hair and see what settings she is using.

Thanks, I will try that.
Linday is a different case. those hairs are made of tubes, not flat cards. Could be, exactly the reason why they're usung tubes instead of cards.

@ felis
Looks so much better for sure.
Thanks :)

Similar options are to reduce gravity, increase bending stiffness, decrease mass per unit area and increase shear stiffness. Each one will affect the hair in a slightly different way and create a slightly different effect. Without trying them all, one at a time, it's hard to get an idea of the effect for each individual hair and then enable you to guess at the combined effect. But it does take a LONG time to do and even then when combining effects, surprises happen.

Linday's use of tubes makes each tube possibly 5-10x stiffer in bending and 2-3x stiffer in shear than a flat card hair would be using the same hair properties - the bigger the tube, the higher the bending and shear strength but lower buckling loads. It's hard to generalise, but those figures might be a good starting point.
