Unreal Engine 4.27 offers many enhancements to GPU Lightmass, including more feature support and increased stability. In addition, our partners at disguise offer a fully integrated ecosystem of hardware, software, and services for connecting physical stages with virtual sets through their RenderStream infrastructure, which has been updated to take full advantage of 4.27 features. Lastly, new Level Snapshots let users easily save the state of a given scene and later restore any or all of its elements, making it simple to return to a previous setup for pickup shots or for creative iterations. There are also improvements for producing correct motion blur in traveling shots, accounting for the physical camera with a moving background. Live Link Vcam, a new iOS app, enables users to drive a Cine Camera in-engine using an iPad. Additionally, 4.27 adds support for OpenColorIO to nDisplay, ensuring accurate color matching of Unreal Engine content to what the physical camera sees on the LED volume.Īlso in 4.27, Unreal Engine’s Virtual Camera system has been significantly enhanced, adding support for more features such as Multi-User Editing, and offering a redesigned user experience and an extensible core architecture. Multi-GPU support also enables users to maximize resolution on wide shots by dedicating a GPU for in-camera pixels, and to shoot with multiple cameras, each with its own uniquely tracked frustum. All nDisplay-related features and settings are now combined into a single nDisplay Root Actor for easier access, and the addition of multi-GPU support now enables nDisplay to scale more efficiently. With the new 3D Config Editor in 4.27, users can more easily design their nDisplay setups for LED volumes or other multi-display rendering applications. That free sample project is now available for the community to download. We recently teamed up with filmmakers’ collective Bullitt to further prove out these tools by making a short test piece and putting the latest production workflow through its paces.

This release introduces a slew of improvements to the efficiency, quality, and ease of use of Unreal Engine’s in-camera visual effects (ICVFX) toolset一making it faster and easier than ever to utilize this revolutionary virtual production technique that is changing the face of filmmaking.
