Back to working on Three.js Fire Pro for a bit.
Doing some explorations on the tooling right now. I added some debug views that let you view different properties of the fluid such as heat, vorticity, smoke, oxygen, etc.
You can view these by slicing the domain and viewing in 2D or as a volumetric rendering.
These are mainly to help me in debugging but I will leave in since they are helpful when authoring the scenes themselves.
