Smoke to points

[bareja]

Hi folks, I'm wondering about how to change smoke simulation to points(particles). I know how to convert smoke simulation when 'smoke object' was created as 'smoke from object'.

I don't know how to convert smoke simulation to particles when fluid emission is from object as source.

Simple Example:

simpleFluidSimulation.hip

Could someone help me, give me advice how to do this ?

Cheers

you want to pass smoke velocity to particles?

simpleFluidSimulation_pops_advect.hip

Thanks! That's it!

another problem, this time with POPs

when i emmitt large number of particles, and my source object move fast, my simulation looks like this:

Is there any option to change particle emission precision ? I've tried change step in animation globals, but without success.

cheers.

EDIT:

sorry, oversamples option in popnetwork

you need to up the oversampling options

Toggle on "Accurate Births" in Source POP's Birth tab.

Be aware, though, it cooks the source geometry once for each particle birthed.

Not a problem for a moving cube, but in a more complicated case it has the ptoential of being a huge slowdown.
