Pyro sim to bgeo.sc vs directly to vdb

Recommended Posts

I can save to bgeo.sc then once the simulation is cached I can read it with a file and convert to vdb, this takes longer (two steps). 

The initial sim with bgeo.sc is already using maximum RAM

If I add a convert to vdb before the filecache, does this step take up more memory?

I have started using .VDB instead of .bgeo.sc for all my volume work. Just write directly to .VDB. Give it a try. If you are at maximum ram, and the convert node throws you over the limit, increase your divsize by a little to gain back the memory that you lost.

I can't imagine that you are using all your ram for a single frame of the sim, but anyway you better do some processing before you save the file, either Volume Compress or convert to vdb or both, so if your target format is .vdb then cache directly to .vdb

The new Pyro Solver Sop or Pyro Postprocess have options for the vdb conversion
