My Vellum hair immediately shrinks in length when I try to sim it.
I've tried stiffness and bend at outrageous settings. As well as constraint iterations up as far as 25000. Substeps, dampening, mass, thickness, changing restlength. Pretty much everything I can think of and it makes no difference at all to the simulation. It's like I'm not even changing any parameters.
I've resampled all my hair curves to have 4, 8 and 12 segments. This also provides very little in the way of changes to the sim.
Unfortunately I can't post a hip file. But if anyone has any suggestions I would be keen to hear them.
Thanks,
WD
