Pyro UPRES

Setup a Pyro as you would normally..This will be your low res sim. In a Geo sop somewhere, make a DopIO node and choose the pyro preset to make sure you're importing all the required fields from the low res sim. You could file cache this out..

Then..make a new Dop network. Inside this, create a smoke object and plug it into a Gas Upres node.
Point the Gas Upres node's Initial Data/Low Res Sop Path to a DopIO node you made earlier. Alternatively if you've cached it out to VDBs or bgeo.sc's you can switch the source to "file" and point it to that cache.


I've found that putting a copy of your low res sim's Source Volume helps a lot. Plug that into the last input of the Gas Upres. Switch it's Velocity setting to COPY, since you'll want to copy it from the lowres sim.

You might have to play with the smoke object's initial size settings, so that it encompasses your entire sim size. Oh - and change the division size to your desire resolution..we are upres-ing after all.

Mess around with extra dissipation or turbulence in the Gas Upres node...

That should be it.
