Full Version: how to Make the softbody less wobbly?

I'm using Obi Softbody to simulate a small bag of sand that can be thrown and shake.
is there is a way to remove the jelly effect? please check the video.

and how to make it behave more like a bag of sand?

thanks

Hi,

Increase the solver's damping parameter to reduce jiggliness. See:

Sand has more plasticity than elasticity. You can control plasticity parameters in the ObiSoftbody component, under shape matching constraints:

Thanks for the help, it's a bit better now, but the bag mesh got broken easily when just rotating the bag, is there a way to make it smooth?

Hi,

Not sure what I'm looking at in the image :/. Rendering issues are usually a result of skinning. Make sure your ObiSoftbodySkinner max distance and falloff are appropriate for your mesh: http://obi.virtualmethodstudio.com/manua...inner.html

Also note that skinning is limited to 4 bone (particle) weights per vertex.

I can take a look at your scene/project if you wish, you can send it to support(at)virtualmethodstudio.com

kind regards,
