maybe this (be sure to check if it is working properly):
var oObject = CreatePrim(Text, NurbsCurve, null, null);
SelectObj(text.isopnt[(3,0.922)], null, null);
AddToSelection(text.isopnt[(2,0.433)], null, null);
AddToSelection(text.isopnt[(0,0.267)], null, null);
Hey Renato,
no...ice modeling is for polygonal meshes only.
Although you can deform them...
just in case you change your mind about using nurbs: https://vimeo.com/43496785
I remember setting a keyframe on the constraint's active param helped
solving these issues in the past.
yep Alan, not using simulated icetrees at all... but thanks for the
reminder.
my problem was updating a rotation value that is relative to a defined
location on a pre-envelope state. So I had to multiply by the inverse first
to get it in local space, then transforn back to world space to apply the
Hi,
I'm setting up a feather system for a bird based on particles.
The basic workflow has 2 stages:
1) grooming/styling
2) follow mesh deformations
step 1 generates an icecache file containing particle rotation and
polygon ref frame on the closest location on emitter at grooming
stage.
step 2
problem solved:
I had to multiply the original particle rotation by the inverse of the
rotation of the closest point on the emitter, then multiply the result
back again to the actual (deformed) rotation of the closest point on
the emitter.
hey Guillaume,
I'm a big fan of your work ever since La Maison.
Thanks for all the help you gave us over these years! Good luck on
whatever may be your next challenges!
wish you all the best...

...try tagging all the polygons extract (delete or keep) freeze.
Now see if you can edit this new mesh.
yes, that was it! The randomize value by range (set to 0 - 1) was
returning -1. So a clamp solved the issue.
Nice you already put this inside your compound. thanks Grahame, this
compound is super!
yes, much appreciated. Thanks!
i have the gut feeling this is something amazing, but i dont
understand a damn thing... lol, me too.
But I think this is a way to use find in array node to find arrays
inside arrays. If so this is very useful indeed. Thanks for sharing
Oleg!
one thing I noticed when recostructing the tree: when
not that I know. You'll always need 2 inputs...that's a shame for a
nodal workflow.
BUT... now with ppg logic you could automate the
creation/connection/deletion of get data nodes with the same value as
your reference port on value change events...same for the inverse
operation. I'll try something
*does not*
oh, I'm almost 100% sure this very same subject came up a while ago
and this was the final word. Maybe this has changed over versions ?
anyways, nice to know! thanks Stephen
oh I see...the problem is the empty mesh.
Try a simple 1x1 grid, apply the projection, freeze. Then build all
your ice road ops (replacing the source geometry).
do the extrusion, now it should work.
can you confirm ?
Chris, thanks for taking a look at it.
Well, maybe I'm missing the concept of point index then.
Is it correct to assume a Point Index is an incremental value assigned to
points, and that there's no gaps between it's values?
example, a pointcloud with 5 particles has point indices 1,2,3,4 and 5.
oh, nice prank setting the simulation scene playback to real time, just
to crash my softimage... =)
other than that, yeah thanks a lot for the files Guillaume!
...or use Momentum, it supports a lot of per point attributes on
softbodies.
I remember some ice related bugs were logged, but they should be fixed by
now.
Of course the bullet cloth solver is not as robust as syflex so it may or
not be an alternative.
well, first thing I'd do is to let clear ICE is a platform and not a
particle simulator.
We all have it embed into our heads, but many who see soft from another
perspective don't, so I think it's crucial to let them know.
other than that it depends: are you presenting ICE or teaching its basics ?
I think you can do it easily with lofts / curve nets + some proportional
tweaks on the mesh...
that's sweet Alan, I'd like to take a look at it.
I mean, if you are allowed to and want to share of course..
