Refinements to Core Rendering Features

In Unreal Engine 5.3, the focus remains on enhancing core rendering features, ensuring that developers can harness their power with ease. One of the standout improvements is in Nanite, which now boasts faster performance for masked materials, including foliage. Thanks to the new Explicit Tangents option, Nanite can represent an even wider range of surfaces, opening up exciting possibilities for intricate world-building.

Meanwhile, Lumen with Hardware Ray Tracing receives expanded capabilities, including support for multiple reflection bounces. What's more, this feature delivers faster performance on next-gen consoles, ensuring that games run smoothly without compromising visual fidelity.

Other notable advancements include Virtual Shadow Maps (VSM), which have graduated to Production-Ready status, Temporal Super Resolution (TSR), Hair Grooms, Path Tracing, and Substrate, all contributing to improved rendering quality and performance.

Multi-Process Cook

Unreal Engine 5.3 introduces a game-changing improvement for content conversion: Multi-Process Cook. This innovation allows developers to leverage additional CPU and memory resources during the conversion process, drastically reducing the time required to obtain a cooked output. Whether you're working on a build farm server or a local workstation, this enhancement streamlines your workflow and accelerates project development.

Cine Cam Rig Rail

For filmmakers and virtual production enthusiasts, Unreal Engine 5.3 introduces the Cine Cam Rig Rail Actor. This feature emulates the traditional camera movement along tracks or dollies, offering refined controls for camera rotation, focal length adjustments, focus distance tweaks, and more. It caters to both in-editor and VCam workflows, providing flexibility and precision in your cinematography.

VCam Enhancements

The VCam system in Unreal Engine 5.3 receives several enhancements to boost productivity. You can now review takes directly on an iPad for faster iteration, stream different VCam outputs to various team members, and even record at a slower frame rate while playing back at normal speed to capture fast-moving action with ease. These enhancements foster collaborative VCam shoots and offer greater creative control.

Experimental Features

Unreal Engine 5.3 doesn't stop at refining existing tools; it also introduces a slew of exciting Experimental Features that hint at future possibilities. While not recommended for production use just yet, these features invite you to explore and provide valuable feedback for further development.

Cinematic-Quality Volumetric Rendering

The release introduces Sparse Volume Textures (SVT) and Path Tracing of Heterogeneous Volumes, two groundbreaking features for cinematic-quality volumetric effects like smoke and fire. SVTs store simulation data, offering new possibilities for rendering volumetric media. Path Tracing enhances rendering quality, bringing global illumination, shadows, and scattering to linear content creation within Unreal Engine 5.

Orthographic Rendering

Unreal Engine 5.3 introduces orthographic rendering, a boon for architectural visualization and stylistic game design. Most modern UE5 features, including Lumen and Nanite, are now compatible with orthographic projections, empowering creators to work efficiently and achieve stunning results directly in the Unreal Editor.

Skeletal Editor

A new Skeletal Editor provides animators with an array of tools for working with Skeletal Meshes. From painting skin weights to final rigging, this editor enables you to perform character workflows entirely within Unreal Editor, eliminating the need for external applications and facilitating faster iteration.

Panel-Based Chaos Cloth with ML Simulation

This release enhances Chaos Cloth with a Panel Cloth Editor, new skin weight transfer algorithms, and XPBD (extended position-based dynamics) constraints. These additions create a non-destructive cloth simulation workflow, balancing speed and precision. Panel-based cloth simulations yield more visually appealing results, and you can now simulate and cache cloth within the engine using the new Panel Cloth Editor and the ML Deformer Editor.
