inflatable wind sock

Recommended Posts

Hi everyone. I'm looking down the barrel at a very cool project that involves creating a CG wind sock and blowing it around in the air. After poking around in Dops for a while I decided it would be a good idea to involve the expert Houdini community.

 

Essentially I need to create a wind sock that has air flowing through it, bending it, flapping it, etc. I also have to animate it like a character. My idea was to create a soft body simulation of some sort that uses a sop animated cage as a target. If anyone would like to prototype it I am attaching a hip file that sets an example scene up. My intention was to post an example of where I was at but my attempts have been so unsuccessful I didn't want to contaminate everyone's thinking. 

 

The sop "TARGET_FOR_DOPS" is just a stand in for the keyframed animation I will need to follow. 

 

Thanks in advance to anyone with any ideas they can share. I'm very grateful as we are a bit of a pickle here.

Houdini grains are really nice to use for cloth type stuff, use the grain sheets and control them with POP forces in DOP's. Here's an example I did for another guy here a while back.

Hehe, exactly, someone asked how to recreate something similar to that in Houdini at the same time as I was heavily into learning the grains, so it was just good timing. :)
