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,
frank

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

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
