Hi everybody,

I'm building a fire effect with hardware particals using multiStreak type.
My emit object is curve with omni emiter. I have experission for mass,opacityPP,
LifespanPP, rgbPP and same fields for movement.

My problem is partical emition type. I want to have a different emition from control vertex of the curve.

I can do it if i create emiters for all control vertex. But i think there is way using
expressions.
Can you tell me What expresssion i have to use?

Please, help me to solve this problem?

Thanks for taking the time with this.

I'm attaching two pictures for details.

hi guys
im not sure whats you mean ,but i think it can help
if the emitter type is omni ,select the curve ,then particle->per-point emission rate

you can chage the rate of per-point on the curve

the control is here:curveShape->extra attributes

hope can help
