rdg Posted February 22, 2008 Share Posted February 22, 2008 still I am very confused about particle setups I emit one particle that collides with a plane. On collision it splits into multiple particles. Those in turn split into a third generation after some time. All particles should be affected by a force. All particles should collide with the plane, but only the source generation should split. The only way I get this done is to have colliders and forces after each split. Now I understand I have to collect the particles as splits seem to be something like a source. I attached a file for demonstration. If you press play every thing seems to behave like expected. After one loop the system stops because of missing groups - something it didn't bother about during the first run. spark.hipnc What am I missing?

rdg Posted February 22, 2008 Author Share Posted February 22, 2008 I guess I don't get the order of execution. I understand this as some kind of "uninitialised variables". Now I added dummy groups before the splitting. They have the right names but no content and are set to "preserve group". Georg Quote Link to comment Share on other sites More sharing options...
Marc Posted February 22, 2008 Share Posted February 22, 2008 Hi Georg Here you go. You can just put them all in one big linear setup and it works fine... (at least, it's doing something. Hopefully it's doing what you want it to do ). spark_fixed.hipnc Cheers Marc Quote Link to comment Share on other sites More sharing options...
rdg Posted February 22, 2008 Author Share Posted February 22, 2008 Here you go. Thanks! I had this before - interestingly in your lineup the split particles react to the force as well. But they don't collide with the mesh ... if I raise their lifespan ... It probably offers more control to have a collisionPOP for every generation? I had the impression that operator after a split only affect particles of this very split. Thats why I started to branch off and recollect. I attached my fixed file: rdg_spark.hipnc Georg Quote Link to comment Share on other sites More sharing options...
Marc Posted February 22, 2008 Share Posted February 22, 2008 yeah you'll have to have another collision pop after the second split. Forces should apply to all the particles, assuming you haven't specified a group. Quote Link to comment Share on other sites More sharing options...
