This project was created using Houdini, Photoshop and Nuke.

After the modeling of the scene, a particle system was created using the normal of the flamethrower to direct the particles towards the
wall.

A pair of metaballs were placed on the wall and used to reinforce the deflection of the particles. The particle system was cached and served as a source for the pyro. Rigid body dynamics are also part of the project. 

Rendered using Mantra.
