Virtual production has forever changed the way we make movies. What once required huge sets, days of on-location shooting, and months of post-production can now be done in real time and with incredible precision.
Unreal Engine, which started as a video game engine, has become an essential tool for creating cinematic environments on set, taking us to a level of creativity and efficiency we never imagined.
Virtual production is a technique that allows entire worlds to be projected in real time onto large LED screens right on the film set. This means that rather than shooting in front of a green screen and relying on effects being added later, actors, director and crew can see exactly what the final environment will look like in real time. Unreal Engine, with its real-time rendering capabilities, has been one of the tools that makes all this possible.
What makes Unreal Engine so special in virtual production?
Unreal Engine is incredibly powerful when it comes to creating virtual worlds in real time. With technologies like Lumen (its global illumination system) and nanite (which allows working with very detailed geometries without affecting performance), Unreal Engine allows us to project realistic environments on LED screens in real time. This has made possible revolutionary projects such as The Mandalorian, where sets are built virtually in a 360° space called “The Volume.”
By using Unreal Engine, the team at The Mandalorian He was able to create planets, cities and spaceships without physically moving around or using green screens, and the result was a visual experience that is simply unlike anything before.
Advantages of using Unreal Engine for virtual production
The advantages of using Unreal Engine in virtual production are many, but there are a few that have truly changed the game in the film industry:
- Save time and costs: With Unreal Engine, entire virtual locations can be created, reducing the need for travel and building large sets. The crew can make adjustments instantly, and each change is immediately reflected on the LED screens.
- Immediate realism for actors and crew: Instead of acting in front of a green screen, actors see the world they are acting in. This allows them to react much more authentically, and helps the camera crew get accurate shots without waiting until post-production to see the result.
- Dynamic lighting in real time: Lighting is something that can make or break a scene. With Unreal Engine, we can modify lighting conditions on the fly. This means we can adjust the light to suit the scene in seconds, without having to wait for adjustments in post-production.
- Changes and tests at the moment: Because the engine allows you to see every detail in real time, directors and production crew can test different lighting, color, and angle options without pausing filming. This speeds up creative work and reduces unforeseen events.
How the workflow works in virtual production with Unreal Engine
It all starts with creating the environments in Unreal Engine, using 3D graphics and detailed textures to build the “world” we’ll see on screen. Then, virtual cameras and lights are set up to replicate the desired shots. Once on set, the physical cameras are synchronized with the environment in Unreal Engine, thanks to a tool called Live Link, which ensures that the movement of the real cameras and the virtual background align perfectly. This way, as the camera moves, the environment adjusts to give the sensation of depth and realism, as if everything were part of a single plane.
Examples of virtual production with Unreal Engine in cinema
In addition to The Mandalorian, other major projects have used Unreal Engine for virtual production. In Westworld, environments were created in real time to transport actors and audiences into complex and detailed worlds. In The Lion King (2019), the team used Unreal Engine to simulate lighting and environments before recording the final version in CGI, making it easier to create a realistic, living world.
Even in Ford vs. FerrariUnreal Engine allowed them to create virtual environments for the racing scenes, saving time and budget while capturing the speed and energy they needed without having to recreate the race tracks physically. This use of the engine helped build intense and captivating visual moments that wouldn’t have been possible otherwise.
The future of cinema: virtual production and Unreal Engine
It’s amazing to think how Unreal Engine has changed film production in such a short time. With virtual production, filmmakers can visualize and experiment with their ideas in the moment, making the creation process more immediate, collaborative, and most importantly, creative. With this technology, we are no longer limited by space or physical locations – the only limit is our imagination.
Unreal Engine has opened up a new world, where stories can come to life in more innovative, immersive and spectacular ways than ever before. Virtual production is no longer just an option; it’s the future of filmmaking, and we’re just beginning to see what can be achieved with this technology.
