Hi, I'm pretty new to Houdini and trying to create a simple vellum stimulation using it.
I was trying to make the 2nd ball stays on top of the 1st ball after it falls like ice cream scoops. I created 2 groups and used tried Vellumglue but not sure why it is not working..Is there any other settings that should be done?? Thank you!!
The working file is attached.
