Dandelion Wire Simulation Jan. 8, 2013, 5:30 a.m.
Hey folks,
I am trying to create a realistic dandelion simulation and beginning to bang my head against the wall/desk.
I'd like to end up with this:
http://www.youtube.com/watch?v=kYAPFztLMJE [youtube.com]
I have attached my (rather tortured) scene attempt.
My method is to bring all the sop geometry in as one big wire sim and affect gluetoanimation and kangular on the fluff/stem.
There are 3 movements that I'm attempting to capture:
1. The twitching of the fluff
2. The bending of the stem while the prongs are still attached
3. The moving of the prong/fluff when they a re broken.
I am achieving the first movement by affecting the wires with wind with random activation (otherwise the wires settle to still) but I don't want this wind to affect the prongs.
Basically I'm all tangled up and if anyone has any ideas it would help me out a lot.
Thanks all

Multiple State Changes In Dops Dec. 11, 2012, 5:06 a.m.
Hi There,
I am attempting to create a scene that will procedurally change an object's physical state based on emergent events (impacts for example).
I'm not too experienced with the dops context but I assume the sop solver is integral.
Here is a dummy scene (hardly worth posting) of a sphere about to hit a groundplane.
How could I set up a network that turned the sphere into a flip fluid when it hits the ground, and continues to evaluate as a flip fluid?
Ideally I would be hoping to extend this to various other dynamic solvers (smoke for example)

File Write Doesn't Work With Python Filename Nov. 7, 2012, 9:37 a.m.
Hi there
I have attached the a simple scene to illustrate my problem.
I am attempting to write a file with a filename copied from a parameter that uses python to generate the filename.
In the attached scene the parameter produces ‘$HIP/pythonTest.bgeo’
When I paste relative the reference using `chs(“../parm”)` I get an error saying on the file node saying “unable to read file ‘$HIP/pythonTest.bgeo’”
If I manually type this in or copy it from a parameter that I type it into it works fine, so I know it has to do with resolving the “HIP…” filename into a full path but I don't know what command I can use to do this.
Thanks a lot
