Do you have bones in that region in your second input?

My guess is that you don't have any hand or feet bones. You'll want to include them if you want your hands and feet included in the tissue sim. If you don't have hand or foot bones you'll want to cut the hands and feet off for your tissue sim, which is what is usually done in production as John mentioned above.

If you do have bones there, then have you tried increasing the rigid stiffness/damping ratio?

Do you have your rigid group enabled and specified on the tissue solver?

Hi Chen,

If you submit a support ticket with your file attached I can take a look, I can't tell what's wrong from the video alone, unfortunately.

Also we get notified about support tickets, but not forum posts, so you'll get a quicker response in future if you submit your question directly to support
