My blend file

I'm playing around with the Softbody engine in Blender to create something like this:

what I'm trying to go for

...but I've had no luck yet. Whenever I try to simulate, I get very strange results like this or this, shown here (links are better quality):

example 1 example 2

Although they're hilarious and fun to show to my friends, they're not what I'm trying to achieve.

  • $\begingroup$ Although I could sit here watching rubber chicken man all day, it wouldn't solve your problem. Could you upload a more informative (albeit not as entertaining) screen-shot of the physics panel for him? Also check to make sure he's not parented to anything. Thanks! $\endgroup$

Okay the problem of flying around appears to be the collision ball size calculation. You had it set to average. When I set it to minimal, it worked. I admit, I have no idea why this happened, it may have been a collision fight with the plane, but changing it does fix your problem.

I also tweaked a few other settings to get it to look like the target animation, it's not perfect, but it's better than what you had. :)

  • Turned off Stiff quads (you don't want anything stiff on this guy.)

  • Turned friction up to 1.00 (that may have been part of your problem, he's as slippery as an eel)

  • Angled him a little so his legs don't fold up. (didn't work real well, but I'm sure if you try you can get it right)

  • And (optional) changed skin texture to something shiny so I could see bounding and stretching problems. (also that skin texture is disturbing :D)

So the effect isn't quite right, but hey! he doesn't head for Florida every time you hit play. Noodling him is your job as the artist. Have fun...

    $\begingroup$ self collision seems to have an effect too, i had better results with minimal. $\endgroup$
