Shot in the dark here, but I always use the "store strand groom" from
melena in my groom ice tree, and then have a simulated ice tree with
"restore strand groom".
I'm doing my fur in houdini at the moment, so I'm a bit rusty on the
workflow, but that's how I remember doing it last year.

Well this is very average scale and centered, as I am in the proces of
rigging and applying fur to the elements. No legacy Hair either - only
ICE, and no simulation for turbulence or the like.

have seen this on some production shots.
because of massive scene size (as in: things happening a long way
from the origin) we ran into limits of floating point precision.
The solution was to offset the whole shot (parent whole scene
under a null) so it was centered around the origin, and rebake all
pointcaches.
incidentally it was hair for feathers on birds – with the erratic
random jitter they were kind of like flapping around in the breeze
– and with the fixed and stable caches the hair/feathers ended up
too stable to my taste.
this was all long before ice and strands – but floating point
precision limits still exist.
if your scene is very big or very small (size not complexity), or
action is happening very far from the origin – that could be the
cause.

Maybe it is not only with fuz.. I'm actually having same issue but
with softmiage hair.
with animated character hairs jitter like changing places in every
frame...
so it maybe is not something from the fuzz...

just out of the blue do zero out any epsilon values in the

I have had the pleasure of testing Paul Smiths excellent
Fuzz for applying fur - great tool with comprehensible
controls for grooming short fur. Unfortunately it looks
like the strands orientation jitter when the generator
surface is animated - deformation as well as SRT. It is
set up for animation, so the strands stay on the deformed
surface, but I have this jitter. Did anyone here
succesfully find a fix for that?
I did write to Paul BTW, but I guess he is busy, so no
reply yet. After all this is a free (donationware)tool so
I am certainly not expecting him to provide support :)
It would be awesome if I could get it working, as it will
be hard to redo the grooming with other tools , plus I
have no time for looking into Kristinka or Melena.
