Best partitioning method for specific fume fx sim?

[romanus]

Hi there,

I’m doing some partitioning, using pflow based on fume fx birth (750 frames-heavy fume fx sim). I wonder if anyone can give some tips on what’s the best method (in terms of optimization/time consuption):

1 - Generate 20 partitions based on pflow + fumefx birth (200.000 rate)

2 - Use the prt fume fx directly from fume fx simulation - this seems to give me really different render results (seems smoke instead of that nebula kind of feeling you have using the other aproach)

3 - Generate 1 partition based on pflow + fumefx birth (200.000 rate) and then create 19 partitions from pflow + prt birth

Thanks for any tip on this,
Cheers

I would vote for 1. and 4. (Use Stoke ).

2. PRT FumeFX does not do the same as PFlow. It places particles in voxels according to the voxel Smoke channel. The particles are not moving, they are coming and going just like using PRT Volume with an animated mesh.
3. There are hacks to do partitioning with PRT Birth, but the results won’t be the same as “real partitioning”.

Hi Bobo,

I’m curious about method 4! Do I have to do one partition first and then use stoke? Or does stoke works directly with fume fx?

Stoke 1.0 works directly with FumeFX simulations:

See also the 3rd Webinar video here (I suggest you watch them all though ):

Stoke 2.0 goes several steps further as it allows the reading of FXD files even without a FumeFX object in the scene, and can both read and WRITE FumeFX files as part of its new Field Editing capabilities. Stoke 2.0 is expected to ship in the next few weeks. The current price is also subject to change, but v1.0 users will get it for free…
