Hi Emilio and Oscar:
If that's the case, I'll polish up the animation first, then cache it
out and use that result to drive the cloth simulation rather than doing
it all in one scene.
I'm still going to try and see if I can solve this problem within a
referenced workflow though when I get some spare time...I think I must
have overlooked something wrt to the way I set up the Syflex ICE tree.
(Otherwise if I don't get this working, I'll never hear the end of it
from my professor about nCloth being superior =P )
@ olivier: Hi Olivier, I actually ran into that problem in the main rig
scene; as you said, copy/pasting the tree resolved it. :D In this case
though because the ICE tree is referenced, I wasn't able to do that in
the animation scene...but what I'll probably do is delete the ice tree
from the referenced model, re-create the tree in the animation scene
itself, and see if that works.
Thanks for replying guys! Have to admit caching the animation itself
wasn't the first thing that came to my mind. Again, sorry to bother with
such a simple simulation question, but it's hard to find resources on
Syflex....
Yours sincerely,
Siew Yi Liang

I remember having sometimes weird issues (simulation behaving badly)
when changing topology of a syflex sim (for example increasing a grid
density) or copying the ice tree to another object.
Usualy copying the whole tree deleting and pasting in a fresh new
icetree solved the problems.

What we do is always simulate in another scene, since we point cache
everything, we cache the simulation scene and load that cache in the
lighting scene, so we avoid issues with simulation and referenced models.

Stupid question maybe but have you baked the syflex sim before
importing as a reference model?

Hi all:
I'm working on a little test animation in XSI where a guy
wearing some pants is doing acrobatics, and I was playing
around with Syflex in order to get some cloth simulation
going for fun. Right now, I have a main scene file that
contains the rig with a Syflex ICE tree, and the simulation
works fine there. However, once I export it to a model and
replace the path of the referenced model in the scene that
contains my animation, the simulation fails to behave as
expected. Additionally, I've noticed some of the changes I
made to the rig seem to be broken in the referenced scene
(mostly custom params that I created for the DisplayInfo in
order to tweak the sim). Additionally, the sim appears to
behave entirely differently than in the original rig scene.
(I tried doing a rough animation in the original scene file
to test the sim behaviour and it behaved as expected)
Notably, when I export the model from the original scene, I
get the warning:
// WARNING : 3000 - Model Runner_Rig does not contain all
inputs for object Pants_M_sim_rdrGeo to perform. Imported
model may not behave as expected.
I have no idea what nodes/inputs are missing though. The
entire model afaik should be self-contained, as it's not
referencing anything else.
I tried importing a new referenced model and copying the
animation from the old rig onto the new one: storing an
action and then applying it resulted in odd transfer: the IK
handles had incorrect animation transferred, but most of the
other controls' animation transferred correctly. I tried
copying all the keys from the animated rig via the dope
sheet, but I couldn't paste the keys on the new model; the
option was grayed out (!) I didn't change anything in the rig
hierarchy apart from adding custom params to the DisplayInfo,
so I don't think this is normal...
Does anyone have any best practice guidelines for this where
ref models+Syflex is concerned? I've never run into these
problems with referenced models before, but then again, this
is my first time playing around with Syflex, so I'm not sure
if I've done something wrong here. (Especially wrt updating
referenced models; right now I just basically opened the
model PPG and replaced the filename to point to the updated
model which I've always been doing. Is this possibly causing
the issue?)
Thanks!
