afx Posted March 14, 2009 Share Posted March 14, 2009 (edited) Probably a very easy way to do this but cant seem to come across a visibility node in Pops. Needed particles to basilly turn on and off over time randomly. Edited March 14, 2009 by Angelo Quote Link to comment Share on other sites More sharing options...
old school Posted March 15, 2009 Share Posted March 15, 2009 Do it after the Particle sim with a Delete SOP. Create your delete condition attribute or put them in a group inside POPs. Then with a Delete SOP use expression to work with attribute or group to work with group. Another way is to create Alpha and flip it from 1 to 0 when you want them to disappear. This requires the shader picking up the default Alpha attribute. Quote Link to comment Share on other sites More sharing options...
