Will Real-Time Digital Sets Replace Green Screens?
Disney, Netflix, Amazon, Paramount, and more are betting big on digital sets, Volumes, and digital set extensions. Let’s take a look.
Practical meets virtual. Digital sets are here to stay, and thanks to COVID-19, they’re being adopted at a much more rapid pace. Also dubbed XR, or cross-reality, these systems combine physical set pieces, cast, and crew, with digital sets or set extensions.
What’s different from traditional rear projection techniques is that these sets are built in real-time game engines, like Unreal Engine. The sets themselves can be altered during a shoot, which also means there’s a new rising role in the production world.
At ILM (Industrial Light & Magic), they call this the Brain Bar—a group of 3D artists and technicians who work on-set with the camera crew and lighting crew to make these systems work.
They work hand-in-hand on set with the gaffers to light the set and match colors, while also working with camera crew to track camera position and lens settings so that the digital displays show at the proper angles, depth of field, exposure, and more.
The biggest challenge? There aren’t enough of these people in the industry. This type of work requires someone with working knowledge of both filmmaking and video game production.
The ILM Volume is a circular set with a seventy-five-foot diameter.
It was originally designed for interactive light with a green screen backdrop that could follow an actor around. That way, there would be no need to re-light screens between takes.
During the production of The Lion King, the film’s VFX team began testing video game engines for digital sets.
The content on the screen was motion tracked to the camera, so that the position of the camera reflects a realistic look to the set through the camera lens. This allows for perspective and parallax changes while filming.
In the simplest way, it’s like being in a large lighting box. Placing a subject in the space realistically lights your subject. And, with Mandalorian’s suit becoming more reflective over every episode, it gave the production team an incredible amount of freedom to light the Beskar helmet and suit.
The real game-changer is that most of the technology isn’t proprietary. LED screens, game engines, and 3D environments are all tools people have access to.
ILM is currently constructing three more Volumes across the globe, and studio executives at Netflix, Amazon Originals, and Paramount have revealed they’re also already using the technology, and building studios of their own.
It’s now about getting the artists and technicians in place to push the concepts even farther. So, what are you waiting for?
