true, I have seen that as well. my setup works well enough now, but I
wish those thigns were easier and more intuitive.

I've found that the rate channel sometimes has trouble with bounding
boxes, specially when using rotoshapes to drive it. Have you tried
setting the bbox to the resolution area? It's something to try, at least.

hm, yeah, it does seem to work. yesterday's set up didn't for some
reason, but now it works better.
Forgot about the ParticleSetup node, that certainly helps.
For some reason I can't use a rate channel in combination with
emiter_order set to "randomly". All particles simply vanish when I do.
Will have to work around that one for now.
Anyway, thanks for the reply. I really hope we will see some
improvements with the particle system, along with better
rotational control and support for clustering etc.
Cheers,

I think transfer velocity seems to work for this application? I
made a quick little test, but maybe it isnt what you are after.
But maybe the expression can be helpful.

Has anybody had success in setting up a particle system that
"flicks" particles off an emitter?
I need an effect that looks like when you flick paint of a
paint brush, i.e. the emitter moves fast (card rotating 180
degrees), and I need it to emit particles that inherit it's
speed when they are born. The "transfer velocity" knob seems
to transfer velocity from the emitter to the particles even
when they are already born and "detached" from it, which is
kinda rubbish.
Animating the "transfer velocity" knob doesn't work either
(and it wouldn't help much anyway, since the animation would
be global, not local and relative to each particle's life).
Does anybody have any ideas how to achieve this? The only
thing I can think of is giving the particles an initial speed
and fudge it until it kinda looks like they are being
flicked, but that always looks rubbish as well. A clever
expression maybe?
Cheers,
frank
