Particle FXs

Ok I'm making an exhaust FX for my BM21 and I somehow can't get it to work correctly, I wanna make a flame that is big and fat at the start, and then gets thinner and thinner. Somehow I get that effect only when the weapon is fired, then the FX just goes into one big fat thing.

The thing I wanna make:

The things I have made:

For you code you should make negative SizeRate values to make the particle shrink over time. Ofcourse by doing that you would need to set Size to the biggest size. Also lower your burstCount to something like 2 or 3, maybe even 1. That'll reduce the laggyness when you have more then 4 missiles flying around (unless that'll be usually the max).
