Supercell hired Buck to create an entirely 3D animation to advertise their new holiday skins for the winter holidays. I was tasked with creating various snow effects for the animation.
For the snow explosion, I employed a few different experimental techniques to assemble it. The base of the simulation actually starts as procedurally generated ballistic paths. I was able to shape and distort these ballistic paths to better match notes about shape and size of the explosion without needing to worry about the physics of creating such shapes.
I then used the ballistic paths to instance and move chunks along them in a semi-physical but mostly controlled manner. This animation was then used to advect and generate the snow volume smoke simulation.
Because this effect worked best as combination of volumes and particles/geometry, I then used the snow simulation to advect the particles of various masses to achieve a unified motion and look.
