Unreal Engine 5.3 Download | TechSpot

Unreal Engine enables game developers and creators across industries to realize next-generation real-time 3D content and experiences with greater freedom, fidelity, and flexibility than ever before.

What is Unreal Engine?

Unreal Engine is a 3D game engine developed by Epic Games, developers of Fortnite. The Unreal Engine is now in its fifth iteration, having been around since 1998, it’s one of the most established and well regarded game creation and 3D visualization tools. Unreal Engine has been used to create many popular games like PUBG, the Final Fantasy VII Remake, Street Fighter 5, Borderlands 3, Gears 5, Batman: Arkham City, and Valorant.

How many GB do you need for Unreal Engine?

Once installed, Unreal Engine 5 will take up anywhere from 50GB to 120GB but you will need more free space to save your projects. For a smaller game you might fit into 10-50GB, depending on the assets. All in all, working with a 512GB drive may be sufficient, but 1TB or 2TB is recommended.

What are other Unreal Engine 5 system requirements?

For PC, you need Windows 10 64-bit or newer, a quad-core Intel or AMD CPU that is 2.5 GHz or faster and 8 GB RAM. For macOS, you need Big Sur, quad-core Intel 2.5 GHz or faster and 8 GB RAM. For Linux, Ubuntu 18.04, a quad-core Intel or AMD 2.5 GHz or faster and 32 GB RAM.

Does it cost to use Unreal Engine 5?

Unreal Engine is free to use for creating linear content like films, and for custom and internal projects. It’s also free for startup game development. A 5% royalty kicks in if and when your title earns over $1 million dollars.

Which is easier to use, Unity or Unreal Engine?

There is no right answer to that question. Both game engines are extremely robust and offer a fully featured free version to get you started. Both have strong communities in which you can participate and consult with. The general consensus at this stage is that Unity and Unreal Engine both are beginner friendly and won’t require advanced programming knowledge for simple projects which will get the ball rolling as you learn.

What’s New:

Unreal Engine 5.3 Release Notes

We’re excited to announce that Unreal Engine 5.3 is now available. This release brings numerous wide-ranging improvements as we continue to expand UE5’s functionality and potential for game developers and creators across industries.

As well as enhancements to core rendering, developer iteration, and virtual production toolsets, we’re introducing Experimental new rendering, animation, and simulation features to give you the opportunity to test extended creative workflows inside UE5 – reducing the need to round-trip with external applications.

Refinements to core UE5 rendering features

With this release, we’ve continued to refine all core UE5 rendering features to address our ongoing goal of making it easier for developers to leverage them at higher quality in games running at 60 fps on next-gen consoles; the improvements also offer higher-quality results and enhanced performance for linear content creators.

Specifically, Nanite has faster performance for masked materials, including foliage, and can represent a greater range of surfaces due to the new Explicit Tangents option, while Lumen with Hardware Ray Tracing has expanded capabilities that include multiple reflection bounces, and delivers faster performance on consoles.

Other areas with notable advancements include Virtual Shadow Maps (VSM) – which is now Production-Ready – Temporal Super Resolution (TSR), Hair Grooms, Path Tracing, and Substrate.

Multi-Process Cook

In another useful improvement, developers can now leverage additional CPU and memory resources when converting content from the internal UE format to a platform-specific format, significantly reducing the time it takes to get a cooked output from a build farm server or on a local workstation.

Enabling Multi-Process Cook launches subprocesses that perform parts of the cooking work alongside the main process. Developers can select how many subprocesses they want to run on a single machine.

Cine Cam Rig Rail

Filmmakers can now emulate the workflow and results of traditional camera movement along tracks or on dollies, thanks to a new Cine Cam Rig Rail Actor.

The Cine Cam Rig Rail provides more refined controls than the existing Rig Rail, including the ability to choreograph settings like camera rotation, focal length, focus distance, and so on, at different control points along the path. It supports both in-editor and VCam workflows.

VCam enhancements

Talking of VCam, enhancements to the system in this release include the ability to review takes directly on the iPad for faster iteration; to simultaneously stream different VCam output for different team members – for example, with camera controls for the camera operator, without for the director – facilitating collaborative VCam shoots; and to record at a slower frame rate and play back at normal speed for easier capture of fast-moving action.

Experimental features

As well as these updates to core toolsets, Unreal Engine 5.3 introduces a number of exciting new Experimental features, which we expect to further develop in future releases. We’d love you to try them out and send us your feedback, but we don’t recommend using them in your productions just yet.

Cinematic-quality volumetric rendering

Two new features, Sparse Volume Textures (SVT) and Path Tracing of Heterogeneous Volumes, introduce a number of new capabilities for volumetric effects such as smoke and fire.

Sparse Volume Textures store baked simulation data representing volumetric media, and can be simulated in Niagara or imported from OpenVDB (.vdb) files created in other 3D applications.

In addition, more complete support for rendering volumes is now available as Experimental in the Path Tracer. This offers the potential for high-quality volumetric rendering – including global illumination, shadows, and scattering – for cinematics, films, episodic television, and other forms of linear content creation directly in UE5.

Real-time use cases such as games and virtual production can also begin experimenting with SVTs for playback of volumetric elements, although performance is limited at this time and highly dependent on the content.

Orthographic rendering

Starting in UE 5.3, we’re introducing orthographic rendering; this is useful for visualizing architecture and manufacturing projects, as well as offering orthographic projections as a stylistic camera choice for games.

Multiple areas of the engine have received attention to achieve parity between perspective and orthographic projections. Most modern features of UE5 are expected to now work, including Lumen, Nanite, Shadows, and Temporal Super Resolutions. Orthographic rendering is also available in the Unreal Editor, enabling users to make updates in a live setting.

Skeletal Editor

A new Skeletal Editor provides animators with a variety of tools for working with Skeletal Meshes, including the ability to paint skin weights.

Whether for quick prototypes or final rigging, this enables you to perform more character workflows entirely in the Unreal Editor without the need for round-tripping to DCC applications – so you can work in context and iterate faster.

Panel-based Chaos Cloth with ML simulation

Also designed to enable you to bring more of your creative workflows directly to UE, this release sees some updates to Chaos Cloth.

We’ve introduced a new Panel Cloth Editor and new skin weight transfer algorithms, and added XPBD (extended position-based dynamics) constraints as a basis for our future cloth generation in engine. This provides for a non-destructive cloth simulation workflow in which you can trade off speed for precision. In addition, the use of panel-based cloth can result in better-looking simulations.

Cloth can also now be simulated and cached in engine using the new Panel Cloth Editor in conjunction with the ML Deformer Editor.

nDisplay support for SMPTE ST 2110

And finally, in preparation for the next generation of LED production stages, we’ve added Experimental support to nDisplay for SMPTE ST 2110, utilizing NVIDIA hardware and Rivermax SDK. This lays the groundwork for a range of hardware configurations that open up new possibilities for LED stages – the most exciting configuration uses a dedicated machine for each camera frustum, maximizing the potential rendering resolution, increasing frame rate, and allowing for more complex scene geometry and lighting than previously possible.

This solution offers the ability to tackle challenges like wider angle lenses that require greater resolution and multi-camera shoots that stress current systems. It also implies lower latency in the system, due to simplification of the signal chain.

Unreal Engine 5.2 Release Notes

We’re excited to announce that Unreal Engine 5.2 is now available. With this release, we’ve further expanded UE5’s groundbreaking toolset as it continues to deliver on the promise of making Unreal Engine the most open and advanced real-time 3D creation tool in the world.

Alongside feature refinements and stability improvements, Unreal Engine 5.2 pushes the boundaries of what creators can expect out of the box, delivering innovative new functionality.

Procedural Content Generation framework

Unreal Engine 5.2 offers an early look at a Procedural Content Generation framework (PCG) that can be used directly inside Unreal Engine without relying on external packages. The framework includes both in-editor tools and a runtime component.

The PCG tools enable you to define rules and parameters to populate large scenes with Unreal Engine assets of your choice, making the process of creating large worlds fast and efficient.

The runtime component means that the system can run inside a game or other real-time application, so that the world can react to gameplay or geometry changes. The PCG tools can also be used for linear content requiring substantial numbers of assets, such as large architectural projects or film scenes.

This is an Experimental feature that will be further developed over future releases.


This release also introduces Substrate, a new way of authoring materials that gives you more control over the look and feel of objects used in real-time applications, such as games, and for linear content creation.

When enabled, it replaces the fixed suite of shading models with a more expressive and modular multi-lobe framework that provides a greater range of surface appearances and a wider parameter space from which to work. It is especially powerful for describing layered looks, for example “liquid on metal” or “dust on clear coat.”

To test out Substrate, you can enable it in the project settings. As an Experimental feature, we do not recommend using it for production work; we welcome feedback to continue to refine its functionality.

Enhanced virtual production toolset

With this release, the virtual production toolset continues to receive new features and enhancements that give filmmakers more creative power.

Dovetailing with the desktop ICVFX Editor, a new iOS app for ICVFX stage operations (coming soon for iPad via the Apple App Store) will offer an intuitive touch-based interface for stage operations such as color grading, light card placement, and nDisplay management tasks from anywhere within the LED volume. This puts creative control directly in the filmmakers’ hands to achieve the desired look where filming is actually taking place, without having to call back to the Unreal Engine operators.

Meanwhile, enhancements to Unreal Engine’s VCam system offer filmmakers greater scope for creative decision-making during pre-production. These include the new ability to operate multiple simultaneous Virtual Cameras off a single editor instance, as well as to create more sophisticated and layered camera moves.

Finally, extended nDisplay support for SMPTE 2110 builds on the initial groundwork laid in Unreal Engine 5.1 toward the next generation of ICVFX hardware deployment. This Experimental feature is suitable for testing in Unreal Engine 5.2 as hardware becomes available, with production viability targeted for Unreal Engine 5.3.

Apple Silicon support

Native support for Apple Silicon has been added to the Unreal Editor. This brings a better user experience, improved performance, and greater stability. The Universal Binary of Unreal Engine that natively supports both Apple Silicon and Intel CPUs is now available to download from the Epic Games launcher.
