Particles and Pyro FX

Hi!

I am trying to create some smoke for an independent short. I have actually made a lot of progress. However, the director wants the smoke to have a lot of streamers and tendrils of smoke that descend downward. I have tried to create this by dumping particles into the simulation, but I cannot get the particles to interact with the sim. Any hints? Is this right method for getting the effect I want?

Hey cspears,

I got this from Fomal:

Basically, you need your particles to be continuously updating your DOPs sim. First, you need to read in the geometry into the volume using the SOP Geometry node that has the time continously being updated. Then you need this particle data to affect the velocity field of your simulation using a Gas Particles to Field node.

I've revised your file with these changes. Just run the sim and it will eventually move with the particles. I'm sure there are other ways to do it, but this was the first thing that popped into my head.

HTH
