Hi

Is there any way to vary the size of particles being emitted from a single surface emitter, as they are being emitted?

I guess what I'm really after is an expression which varies the size of the particles at the time of their creation only. I tried writing an expression which randomized the scale of the particles, but they were changing size on *every* frame.

Anybody have any suggestions?

Thanks.

hi,

add a creation expression to you particleShape
eg (for spherical shaped particles)

particleShape1.radiusPP = rand(1,5);

will emit particles wich size differs from 1 to 5

cheers, carsten
