An engine operator is a crucial crewmember responsible for maintaining and operating the real-time engine within the volume, and loading and operating assets. But what does that mean in practical terms?
In short, an engine operator serves as the conduit between what’s being rendered onscreen and the actual physical environment on set. They manage all aspects of virtual production from prepping virtual sets to calibrating cameras and ensuring scenes look exactly as desired during filming. It’s their job to use specialized software, such as Unreal or Unity, to build virtual worlds and characters from scratch in order to be rendered live with no post-production necessary. To do this well, there are certain skills that should be honed specifically for virtual production.
For starters, strong technical knowledge is required—engine operators need to be experts at 3D modelling software like Maya or Max, plus highly proficient in programming languages like C++ and Python. Beyond technology though, they must also possess artistic sensibility to craft environments that are visually pleasing yet realistic. And because they're often working with actors or other performers, they should also have excellent communication skills to direct people smoothly while setting up a shot or making adjustments in real time.
On set, the engine operator would help stage the scene by creating virtual lighting and controlling the real-time camera feed into the headset monitors. They'll check the tracking markers before each take, adjust parameters if needed (e.g., lighting levels), and make sure everything works properly during shooting. Afterward, they'd work to clean up any residual noise or artifacts left over from recording and prepare the next scene for filming.
The engine operator is a vital role within virtual production teams, requiring both technological know-how and creative finesse to ensure a seamless experience. With their combination of problem solving, communication and artistry, engine operators bring life to the virtual worlds made possible by cutting edge technology.
