Using simulated guide hairs, fur does not move correctly

Hi all,

I am posting a file where I'm trying to get a curve shaped in a nice curl to be my guide hairs for the fur sop. I simulated the curve and it looks fine in dops, but when I turn the fur node on the fur isn't following along the way it should. Instead its going crazy. The file im sending is simplified and similar to the situation I am in. My actual project involves a horse but in this example file i am using a sphere and getting the same result. Perhaps some one can shed some light on the issue. :roll:

I'm getting this same problem even with the new Fur shelf tools in the latest version of 9.5! Try this, put hair on a sphere rotating in z, add dynamics, and the hair at the top always spins and flips over. Is this a problem in the quaternion math or something?

Fur SOP uses the guide hairs to figure out the general bends and segment lengths to put into a volume of hair. They guide the bends and segment lengths of generated hairs, not define a volume containing them. Moving high frequency effects such as curls and frizz to a shader used by the Fur SOP will likely produce better results.
