make sure you skin have rest.
is the same as if you scatter after geometry, hair will scatter first and then move the points base on the rest vs animated

i think i got it, maybe i needed an additional constrain to pin to target and just select the roots so they get glue to the first object they find.

if i attach guide curves into a cloth object but i would like that the guides thickness also be consider in the simulation,
example you have a fur coat that fold in itself in the floor, therefor have thickness there for should not be just flat on the floor is it possible to generate the guides into the same sim loop and add a hair constrain?
i was able to do 2 sims, one for the cloth and a secondary for the guides, but... well the hair won't be considered for the motion of the cloth...
this is a small example.
(thanks, Tamte)

has anyone seen this?
that primuv is not known in the wrangler?
(By curiosity can this be done inside vopsopos? with nodes? )

i been analyzing the scene, since under vellum object we do have "compute missing orientation" thanks i didn't know about the
disableexternal, interesting that with one sub step doesn't consider the root very close to the surface and is all good, with substeps the root been collision does get weird. your pointwrangle deactive the root from been consider, and does work, (just on my craziness moving the lines/hairs farter (than the thickness)) did the trick as well (not that we want that but was just to check)
as always thanks for sharing your wisdom!

... is interesting even trying with the guide deforms adding an orientation, or adding a timeblend to get the substeps at geometry level still same outcome...
i try different combinations and still... with higher substeps hairs are unstable.
could this be a bug?

i just have a ball with hairs, with sub steps of one looks great, if i do 2 sub steps now they are super jumpy and every random frames will kinda pop... 
shouldn't increasing the sub steps ensure this doesn't happen?
any ideas or hint?

make a circle, copy lines to the points in the circle
add mountain sop with animation, add v along the curves
make particles from the circle been advected by the velocity of the curves.

thought was an interesting scene, i think they are still porting mantra features into karma and slowly into xpu, since that one kinda just works with materialsX and i think the standard is behind of what normal vops have.
(Doing shaders in materialX is kinda painful compare normal Houdini nodes. plus, they don't have that many nodes yet.)
just adding some hairs with the new fabio material, / i was bored lol

playing with solaris i have a ball and some curves like fuzzy hairs, i can render if i use mantra, but no idea what i am doing wrong, i assigned the material in the obj node.
is stage i import the scene, but just the ball show up any magical stuff that i need to do to get the curves and assign the material???

make an atribute along the curve, you create a uv base on the curve, pipe that into a ramp parameter and the ramp to a bind node with the attribute you want to drive along the curve

i am not sure if the procedural in solaris is been use, the hair gen of the node is extremly powerfull we just have a display node above the hairGen and a null with the renderflag below. looks like is the same stuff just way easier to set up
