For my first attempt at a pyro simulation in Houdini I wanted to try the well talked about plugin called Axiom which makes pyro easier and more streamlined.
⠀
Simulation was based on the Axiom solver workflow using their nodes, such as Axiom Solver and Axiom Source Shape. I created one primary source emitter with all settings applied that I wanted, which was then scattered to points each frame with a for each loop setup. With a bounding box I cut out all particles not visible in the camera to optimize calculation time. Rendering and shading was done in Karma and was really quick. Final render time was around 2 hours for a 10 second sequence, 256 samples in 1920x1080.
