Flamethrower | Arnold | OpenCL | Sparse Pyro Solver

#Flamethrower #Houdini #Sparse Pyro Solver #Demoreel
After watching the trailer of "How I Became a Superhero", I tried the flamethrower. Although I didn't go for the exact look, Here is my take on a more general, simplified version of the Flamethrower.

The characters and animation are from Adobe Mixamo, The gun I downloaded online. For the simulation, I have used Houdini. The initial plan was to have a lot of smoke with the flame but System Constraints! I have to cut the smoke.

For the parameter around 800 Million Voxels on each grid at 0.05 grid separation.
Simulation time wasn't that bad around 6-7 hours.
Render I tried with mantra but it was too slow, so gone with Arnold.
Around 6 min with CPU, 3-4 min with GPU for the Pyro.
The Light Pass took a while, so I have used heavy Denoise using Optix & Noice.
Compositing is done on Nuke, I have used ACES Color to get a better detail out of the Fire.
