Hello,

I am working with Particles in Carrara Pro 6.

My animation is 10 seconds long. The problem I am having is at the end fo the animation. I want particles to be generated all the way through with no let up. So I set the "Emission time range"  from 0 to 20 seconds. I also set the "Lifetime" to 20 seconds +/- 2 seconds. My rationale is that if I set the time way over 10 seconds I will get the result I want. But the particles always die off around 8 seconds.

Any solutions, suggestions?

Also is there any way to make the particles appear to spurt on and off? Imagine an artery with cells...as the heart beats the cells would move faster and then slower...Is this possible with Carrara particles?

Thanks,

Mike

 Sounds like you're reaching your maximum particle count before the time runs out. Try increasing that. As for the spurting, you can actually get that effect by having a small limit of particles over a longer period of time. The particles need to have a lifetime that exceeds the duration required to achieve maximum particle density.

I actually have a tutorial about just this that I'm trying to get up by this weekend for the Dark Arts :D

You can also keyframe the particle velocity over time to get it to spurt.

Thank you both...your suggestions helped.
