Unreal Engine 5.3 has arrived, and it’s bringing a host of improvements and exciting new features for game developers and creators. This release focuses on expanding UE5’s functionality and potential across various industries, with enhancements to core rendering, developer iteration, and virtual production toolsets.

One of the key highlights of this update is the refinement of core UE5 rendering features. The goal here is to make it easier for developers to leverage these features at higher quality in games running at 60 FPS on next-gen consoles. Not only do these improvements offer higher-quality results, but they also enhance performance for linear content creators. Nanite, for example, now has faster performance for masked materials, including foliage, and can represent a greater range of surfaces with the new Explicit Tangents option. Lumen with Hardware Ray Tracing has also expanded capabilities, including multiple reflection bounces and faster performance on consoles. Other notable advancements include Virtual Shadow Maps (VSM), Temporal Super Resolution (TSR), Hair Grooms, Path Tracing, and Substrate.

In addition to rendering improvements, Unreal Engine 5.3 introduces a handy feature called Multi-Process Cook. This allows developers to leverage additional CPU and memory resources when converting content from the internal UE format to a platform-specific format. The result? Significantly reduced cooking time, whether you’re using a build farm server or a local workstation.

Filmmakers will be pleased to hear about the new Cine Cam Rig Rail Actor, which enables them to emulate traditional camera movement along tracks or dollies. This feature provides refined controls for camera rotation, Focal length, focus distance, and more at different control points along the path. It supports both in-editor and VCam workflows, giving filmmakers greater flexibility and control.

Speaking of VCam, Unreal Engine 5.3 brings enhancements to this system as well. You can now review takes directly on the iPad for faster iteration, stream different VCam outputs for different team members, and record at a slower frame rate while playing back at normal speed for capturing fast-moving action.

But that’s not all. Unreal Engine 5.3 also introduces a range of exciting new Experimental features that are expected to be further developed in future releases. These include cinematic-quality volumetric rendering with Sparse Volume Textures (SVT) and Path Tracing of Heterogeneous Volumes. These features offer new capabilities for volumetric effects like smoke and fire, making them ideal for cinematics, films, episodic television, and other linear content creation directly within UE5.

Another notable addition is orthographic rendering, which allows for visualizing architecture and manufacturing projects, as well as offering orthographic projections as a stylistic camera choice for games. The engine has received updates to achieve parity between perspective and orthographic projections, ensuring that most modern features of UE5 work seamlessly in both modes.

For animators, the new Skeletal Editor provides a variety of tools for working with Skeletal Meshes, including the ability to paint skin weights. This enables more character workflows to be done entirely within the Unreal Editor, eliminating the need for round-tripping to other applications and speeding up iteration.

Unreal Engine 5.3 also brings updates to Chaos Cloth, with the introduction of a new Panel Cloth Editor and new skin weight transfer algorithms. The use of panel-based cloth can result in better-looking simulations, and cloth can now be simulated and cached in-engine using the new Panel Cloth Editor in conjunction with the ML Deformer Editor.

Lastly, in preparation for the next generation of LED production stages, Unreal Engine 5.3 adds Experimental support to nDisplay for SMPTE ST 2110. This opens up new possibilities for LED stages, allowing for dedicated machines for each camera frustum, higher rendering resolution, increased frame rate, and more complex scene geometry and lighting. This solution addresses challenges like wider angle lenses that require greater resolution and multi-camera shoots that stress current systems, while also reducing Latency in the system.

These are just some of the exciting features and enhancements in Unreal Engine 5.3. To explore the full list, be sure to check out the release notes.

Background Information

About Focal: Focal is a French audio company established in 1979. It is highly regarded for its high-fidelity audio products, including speakers, headphones, and professional audio equipment. Focal is known for its commitment to audio purity and innovation, and their products are favored by audiophiles and professionals alike.

Technology Explained

CPU: The Central Processing Unit (CPU) is the brain of a computer, responsible for executing instructions and performing calculations. It is the most important component of a computer system, as it is responsible for controlling all other components. CPUs are used in a wide range of applications, from desktop computers to mobile devices, gaming consoles, and even supercomputers. CPUs are used to process data, execute instructions, and control the flow of information within a computer system. They are also used to control the input and output of data, as well as to store and retrieve data from memory. CPUs are essential for the functioning of any computer system, and their applications in the computer industry are vast.

Latency: Technology latency is the time it takes for a computer system to respond to a request. It is an important factor in the performance of computer systems, as it affects the speed and efficiency of data processing. In the computer industry, latency is a major factor in the performance of computer networks, storage systems, and other computer systems. Low latency is essential for applications that require fast response times, such as online gaming, streaming media, and real-time data processing. High latency can cause delays in data processing, resulting in slow response times and poor performance. To reduce latency, computer systems use various techniques such as caching, load balancing, and parallel processing. By reducing latency, computer systems can provide faster response times and improved performance.

Ray Tracing: Ray tracing is an advanced rendering technique used in computer graphics to simulate the way light interacts with objects in a virtual environment. It traces the path of light rays as they travel through a scene, calculating how they interact with surfaces, materials, and lighting sources. By simulating the complex behaviors of light, ray tracing produces highly realistic and accurate visual effects, including lifelike reflections, shadows, and refractions. This technology enhances the overall visual quality of images and animations by accurately replicating how light behaves in the real world, resulting in a more immersive and visually stunning digital experience.
