Hi guys, i'm fairly new to Houdini. I have some questions and hope you guys can help me out with ?

I have a statue modeled in Maya and imported it in Houdini. I've created points onto it and also a “Green virus” spreading across to the nearest points around it. I am trying to get the “Green virus” to fall according to gravity as it spreads in DOP network,but it wouldn't fall. I've tried on some tutorials (foreach node,active value node) given with basic geometries and it worked fine, but when applying the method onto my statue object, it doesn't.

Any ideas ? Thanks alot !

Can you post a hip file?

Hmm, i'm sorry about that. Here's the hip file. Thanks !
