Bend Pyro Import!

[Atom]

I'm trying to use the SOP Bend node to bend the results of a pyro simulation.

I have a basic setup, that is close, but I don't know how to apply the new, bent bounding area to the existing pyro. This results in the pyro being clipped. Is there a way to expand this box based upon the new bent area?

Hi Atom,

here's a simpler way to achieve the same effect with a better volume quality:

I've made the changes to your .hip file:) Let me know if you have any questions! By the way are you the same Atom as from BlenderArtists forum?

Cheers,

Luca

Yep, that's me on BA, too. I've been looking at the new 2.8 offerings, Eevee.

Thanks for the file. I am still getting up to speed, with volume wrangles and your example helps. I have extended the wrangle, to include the temperature and heat fields as well. I think it might even be possible to replace the bend with a point deform and send the entire simulation down a path.

Ah cool to know  

Yes, it should be possible to make a volume defomer via this method! The "Only Output Created Geometry" checkbox is a handy feature in the volume wrangle for these kind of setups.

Holy Shi* you guys are sick, how did I miss something like this!  Sim one plume of smoke, bend and warp tons of instances, done!

I made some progress on bending the pyro along a path. Extreme bends in the curve, reveal the rasterization, however.

I pulled in a path deform subnet that I found at this link.

Here is a single pyro simulation randomly rotated and randomly retimed along random length paths that are randomly deformed.
