The fire effect was split into 4 or 5 sections to make it more directable and less heavy in the simulation. The fire was simulated on GPU with the Axiom solver instead of the traditional Houdini solver because it's more efficient in my opinion. The fire had to behave kinda realistically so I created all the necessary VDB collisions and had to make sure that the fire does not emit any smoke. The scenes were rendered by Dominik Valachovic in Blender. The fire simulations were exported and written out of Houdini by a simple expression frame by frame to an openVDB sequence so he was able to open it in Blender.
There were also some sections where the parts of the body had to be tracked and then from the tracked geometry was emitted the fire.
