Hi. I have next question. I create my scene by tutorial Eduard Schulze. Export velocity and smoke channels. But ffx particles and pflow doesn’t matching. Ffx dissipate normally, pflow don’t disappear similarly. Its ok? Can the pflow particles disappear like ffx one without delete op in event? I hope i clear explain my trouble. Execuse me for bad english.

Hi!
Rendering FumeFX voxels and advecting PFlow particles are two very different things, which explains the difference in the results.
In the one case you are visualizing the actual FumeFX simulation, in the other case you are using the channels in the simulation to produce particles that are then moved around by the velocities of the simulation. You can think of it as of the motion of air (wind) blowing autumn leaves - the motion of the leaves will be similar to the wind’s gusts, but not exactly the same.
You can probably use the FumeFX Test operator to check the values in the FumeFX grid and send out particles to an event with a Delete operator when the Smoke or some other value is below a given threshold.
Roger that, thanks a lot.
