raytheon Posted March 1, 2010 Share Posted March 1, 2010 hi all.. I'm just venturing into Houdini after looking at XSI ICE. In ICE they have the notion of particle states. If you have a fluid simulation, modeling each particle's state transitions using a finite state machine seems intuitive. Houdini doesn't seem to have a state machine operator. If i want to progress a particle in a fluid simulation between fluid, spray, mist,... then it seems, going by the SESI "Particle Spray On Waves" example, that i would us a Group node to separate the particles into the various states based on expressions. If i want to perform different operations based on the transition type then it looks like Python or HDK code is necessary. I'm still quite new to this. Does this seem accurate? thx Quote Link to comment Share on other sites More sharing options...
Macha Posted March 1, 2010 Share Posted March 1, 2010 Have you tried the State POP, Event POP, and expressions? Quote Link to comment Share on other sites More sharing options...
