One of my emitters (the one I want to be upfront haves 50/50 in Z within initial location. I placed the other one (the one I want behind the first one) in 60/60 in Z, -60/-60 in Z and also did the same and even with 100 in all 3 parameters (X,Y and Z) but it still didn’t go behind the one emitter and it’s driving me crazy. I’d appreciate the help!
