Bifrost is really quick for that type of work because it’s procedural and I can plug in lots of different bits of geometry and get things moving quickly.” There were approximately five or six simulations in each shot that were composited together for the final look, and everyone was really happy with the end results. Radford continued, “I worked shot for shot, and no one simulation was the end result.

I did that quite a few times, rendered it off, then composited it in.” “To do this, I’d create a simulation, save a particular cache file of where the simulation looked good, then move it around the scene. “The sand needed to look a certain way when it was not moving, so I created the static sand in Bifrost by using cache files,” he explained. To deliver the shots within the tight, Radford used a clever shortcut technique in Bifrost. “I created sand flying everywhere, and though it looked amazing, I got a little carried away and had to work with the client to scale it back a bit.” “These particles were also emitting material point method (MPM) sand, so I essentially had two simulations that I could play with at once,” he added.

I got to work experimenting in Bifrost and reimagined the concept to have the Zen lines build up gradually, shot by shot, forming more slowly over time. “The client had already shot the footage, and the main issue was that each shot was only a second or two long – not enough time to show the sand physically raking into lines. “The initial concept was to create a Zen Garden that would rake into patterns in the ground as the main character walked down the street,” explained Radford. The client brief and art direction presented various challenges for the VFX artist, who had only two weeks to deliver 12 shots with heavy sand simulation. In the short, a flurry of sand particles ripple and form into raked Zen Garden lines. Strangebox VFX artist and freelancer Phil Radford has created a 30-second commercial spot, Finding Your Flow, for Sapporo Beer’s Pure line using the Bifrost particle system.
