Coloring Particles?
 

Anyone can give me a hand? I wanna know how to make a single emitter that randomly emits red and green particles.

I know I can cheat by creating 2 emitters, let one emits red particles and the other one emits green particles. but that sounds very stupid...

Well then try expressions on runtime:

here lots of helpfull scripts about particles regarding different aspects

: change the Value to get the desire color

Good reply!

Also, do a search in the docs for "rgbPP", as that will help you achive "Per-Particle" coloring:)

Have fun!

Thanks for the reply. But I guess I'm too newbie to understand expression script :(. Anyway, I found another way to cheat and the following is what I did:

create a emitter 1st > Color > Add Per Particle Attribute > rgbPP > Create Ramp > assign birthTime in Input V > Edit Ramp, delete the blue color from the default ramp and set the Interpolation to None. Finally add some Noise and Noise Freq to the Ramp for randomness.
:bgreen:

Cool!

Can't wait to see your results!
