Download HDA – version 1.1
On the SOP level it creates a container meant for the source, and in DOPs the container size and position is referenced for the initial settings of the Smoke Object. The Nulls are meant to be piped into your own Fluid Sources.
In DOPs a Gas Resize Fluid Dynamic node is added, and some settings I prefer on the Source Volume nodes are changed.
No artistic changes are made, just technical changes to get simulating faster. I hope to update this HDA with some different common DOP simulation setups.
