Ryan Posted November 13, 2008 Share Posted November 13, 2008 I am trying to copy a popnet onto a grid and use copy stamping to randomize the motion of each popnet. The popnet just contains a source->force. The force POP has some noise. I tried using a stamp( ) on the 'random seed' parameter of the popnet SOP, but I was not successful. I even tried using stamp( ) on the force POP itself. Any suggestions? Thanks Quote Link to comment Share on other sites More sharing options...
graham Posted November 13, 2008 Share Posted November 13, 2008 (edited) Unfortunately the way POPs are designed, it is not possible to copy stamp them. You can sort of hack randomness based on the specific source point by adding a Cd attribute to the source grid points, setting CR as $PT, then inside your pop network you can do rand($CR) in parameters you want to randomize based on the source.

old school Posted November 13, 2008 Share Posted November 13, 2008 You can use multiple POP Merge SOPs and reference a single particle network multiple times. Add as many physical nodes as you want variants. To get variation you can use attributes fed in to the POP Merge SOP then pick up those attributes in the POPs.
