I have successfully integrated Nvidia Flex into Unreal Engine 4.20.3 and use it for fluid simulations.
I was wondering if I can somehow count the amount of particles in a certain volume during runtime?
Say I have two emitters: one for blue particle, the other for red: both land in a big bowl. I would like to be able to tell the mix between the two? for example 2000 blue particles / 1500 red particles. Any idea how to do that? Or any idea where to start looking for an answer to this?
Thanks a lot for any help,
