Unreal Engine 4.27 New Version: Unreal Engine 4.27 arrives with faster light baking, production-ready pixel streaming and more | – Times of India

The new Unreal Engine version 4.27 is now available. This release brings powerful new features for creators. Key features include in-camera visual effects toolset for virtual production, enhancements to GPU Lightmass for significantly faster light baking, integration of the Oodle Compression Suite and Bink Video codecs for free use in Unreal Engine, production-ready Pixel Streaming, production-ready OpenXR support, Datasmith upgrades, among others.
With the new 3D Config Editor in version 4.27, users can more easily design their nDisplay setups for LED volumes or other multi-display rendering applications. 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.

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.
With version 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. Live Link Vcam, a new iOS app, enables users to drive a Cine Camera in-engine using an iPad. There are also improvements for producing correct motion blur in traveling shots, accounting for the physical camera with a moving background.
Unreal Engine 4.27 offers many enhancements to GPU Lightmass, including more feature support and increased stability. The system uses the GPU rather than CPU to progressively render pre-computed lightmaps, leveraging the latest ray tracing capabilities with DirectX 12 (DX12) and Microsoft‘s DXR framework.
For in-camera VFX workflows, GPU Lightmass enables crews to modify virtual set lighting far more quickly than before, making productions more efficient and ensuring that creative flow is not interrupted.
The Path Tracer is a DXR-accelerated, physically accurate progressive rendering mode in Unreal Engine that can be enabled without requiring any additional setup. In 4.27, a range of improvements make the Path Tracer viable for creating final-pixel imagery comparable to offline renderings
Other features include RAD Game Tools solutions integrated into Unreal Engine, Pixel Streaming is now production-ready, with a host of quality improvements and an upgraded version of WebRTC. With 4.27, users can export many more elements to USD—including Levels, Sublevels, Landscape, Foliage, and animation sequences—and import materials as MDL nodes. Also, Epic Online Services are now available in Unreal Engine.
