hello, I'm fairly new to houdini, and trying to learn using help contents provided with the package, along with some tutorials on the internet.

I was trying to make something like pixar did, cutting vegitables. I just started the work on this effect, but I'm stuck on how to mask the groups that are being created by the break node, as i cut the vegitable. I want piece1, piece2…. to be effected by gravity but not the main piece0.

seeking for your help.
