Quote:Unfortunately I couldn´t use tyVortex as a force in Phoenix
I ran into the same issue myself recently, and implemented a Spacewarp wrapper for tyFlow helper forces, that allow you to input them into PhoenixFD.
I'm not sure when the next build will be ready, but if you're working a tight timeline shoot me an email and I'll send you a new build early so you can use that spacewarp feature.
As for dead particles, why not delete or scale down when particles reach a certain low velocity, so you cleanly clear them out without worrying about them. Once exported to tyCache, it also has options to scale particles up from zero after they are born that will respect retiming options on the tyCache (so they'll scale slower if you slow the cache down)...that may help the birth transitions.
Beyond that, gonna need to see a video example of your effect to really know what the issues are.
