Control Source discharge base on nparticle age

Hi,
How can I control the source discharge base on the age of nparticles?
I am pretty bad at expression and tried this:
PhoenixFDSource1.discharge = nParticleShape1.lifespanPP * 50;

but that doesn’t work.

Any tips?

Thanks,

Yannick

This will not work. I’m not sure if we can support such expression at all, must check. Since Phoenix FD was created first for Max, the animation support is very simple - you set the “Time Base” attribute to “Particle Age” and that’s it. It’s a bit limited, but for your purpose, it should do.

Ok thanks
