Damo Posted February 17, 2008 Share Posted February 17, 2008 Hi, If I have an emitter which emits from frame 1 to frame 50 and the animation continues to frame 100, but I want all the active particles to freeze at frame 50 in a state of 'suspended animation' how would I achieve this? Thanks Quote Link to comment Share on other sites More sharing options...

Thanks Im very new to houdini, but from what i understand you can make a vex op. If time > 50 then V=0,0,0 Quote Link to comment Share on other sites More sharing options...
old school Posted February 18, 2008 Share Posted February 18, 2008 Actually killing the velocity is way to harsh but it would work. The proper method is to use particle states with the State POP. To put a particle in suspended animation, first put it in to a group with an expression then put down a State POP and reference that group containing particles you want to stop, enable STOP and set it to 0. See the example file and read the comments on the POPs as to how I like to manage the particle stop state. stop_state_example.hip Quote Link to comment Share on other sites More sharing options...

Marc Posted February 18, 2008 Share Posted February 18, 2008 yeah stop is what you want. Killing the velocity will cause other problems down the line. Quote Link to comment Share on other sites More sharing options...
