Unreal Engine 5.8 Released

We’re excited to announce that Unreal Engine 5.8 is now available. Download now on the Epic Games Launcher, GitHub, or our Linux page.

UE 5.8 pushes performance and customization further with advanced worldbuilding and terrain creation, real-time vegetation authoring, and streamlined lighting workflows. Build characters and animations faster, easily scale high-fidelity digital humans, and accelerate workflows with the integrated MCP plugin for LLMs.

You can check out the full release notes here, with some highlights picked out below!

Create expansive open worlds

Mesh Terrain is a new 3D mesh-based landscape system that makes it faster and easier to create detailed environments of any scale. Build complex terrain like cliffs, overhangs, caves, and more—without the limitations of traditional heightfields.

Updates to the Procedural Content Generation (PCG) framework give you greater creative control and scalability with nondestructive manual editing, richer procedural environments, and streamlined graph workflows that are easier to build and manage.

The Procedural Vegetation Editor (PVE) enables you to create high-quality, biologically accurate, Nanite-ready vegetation assets that react to wind systems—directly within the Unreal Editor.


Streamline character and animation creation

Character creation and animation are faster and more intuitive in Unreal Engine 5.8, with new tools that reduce reliance on external applications and provide greater creative control directly in the editor.

Expanded Skeletal Editor tools make it easier to sculpt faces, correct poses, and customize MetaHumans directly in Unreal Engine.

Enhanced Control Rig Physics and the new Dynamics solver give animators greater control over dynamic motion, blending physics-based reactions with keyframed animation for more realistic and responsive characters.

Direct Mesh Controls mean animators can interact directly with a character’s mesh, reducing viewport clutter and making facial and performance animation faster and more natural.


Advance real-time rendering

Unreal Engine 5.8 continues to push real-time visual quality while improving performance across platforms.

MegaLights is now Production-Ready, making it possible to add large numbers of dynamic shadowed lights to scenes with less noise, improved image quality, and optimized performance. It’s designed to help teams reach 60 FPS targets on current-generation consoles.

Lumen Lite delivers lighting that is up to twice as fast as Lumen High Quality, helping developers target 60 FPS on handheld devices and lower-end PCs while preserving artistic intent.

The new Toon Shader makes it easier to create stylized visuals inspired by anime, cartoons, and hand-drawn art styles, while Fog Screen Space Scattering enhances fog, smoke, and dust with more realistic lighting and atmosphere.


Scale realistic digital humans

MetaHuman 5.8 expands what’s possible for creating, populating, and animating digital humans at scale.

MetaHuman Collections make it easy to populate real-time worlds with scalable crowds, balancing visual fidelity and performance across mobile, console, and high-end platforms.

Mesh to MetaHuman is more powerful than ever, enabling you to turn almost any human mesh into a fully rigged MetaHuman. Support for arbitrary body and head topology makes it easier to convert scans, existing characters, and assets from external tools into production-ready digital humans.

MetaHuman Animator now supports markerless motion capture, enabling full-body and facial performance capture using something as simple as a single webcam.


Speed up mobile development

Mobile workflows are now faster and easier from setup through deployment.

Automated Android SDK setup simplifies workstation configuration, while faster cook times reduce iteration delays by avoiding unnecessary asset recooking.

With the new Unreal Engine Remote app, you can test mobile input directly from the editor, while improved Platform Preview provides a more accurate representation of how your game will look on target devices. Updated mobile documentation also offers end-to-end guidance for setup, development, debugging, optimization, and shipping.


Accelerate virtual production

Virtual production and cinematic teams can take advantage of more refined and robust rendering tools, improved visual fidelity, and more streamlined performance capture workflows.

Movie Render Graph is now Production-Ready, delivering a flexible, graph-based approach to cinematic rendering with simplified setup, expanded render layers, and advanced post-production controls.

Accumulation Depth of Field delivers more cinematic, film-style focus effects with higher-quality rendering and fewer visual artifacts—without requiring Path Tracing.

Live Link Hub is now Production-Ready, bringing performance capture tools into a single interface with centralized device control, synchronized recording, and live multi-camera monitoring.


Simplify creative iteration

New tools in Unreal Engine 5.8 help teams iterate faster and take advantage of emerging LLM-powered workflows.

The new MCP plugin connects LLMs directly to Unreal Engine, enabling automated asset creation, testing, optimization, and project interaction across core engine systems.

The new Editor Gizmo System delivers a more consistent and intuitive editing experience with improved precision, clearer visual feedback, customizable controls, and better reliability across the editor.


Iterate physics assets faster

Physics-based content creation is more flexible and efficient..

Dataflow is now Production-Ready, making it easier to create and iterate on physics-based assets with a flexible node-based workflow, enhanced usability, and deeper integration with Cloth and Destruction tools.

Chaos workflows continue to evolve in 5.8. Dataflow now streamlines large-scale destruction with nondestructive Geometry Collection authoring, while the new Production-Ready Chaos Cloth Panel Editor provides a more intuitive, panel-based approach to creating and simulating clothing.

Did you guys really name the plugin for all the LLM and all the AI stuff “MCP”? Just like the villian from the old TRON Movie? MCP = Master Control Program? :laughing: Whelp, lets see, how long it takes for it to take over the grid :melting_face:

Do you know that a single preview will have long-term consequences?

CPU Lightmass broke a bit more in this release:

Steps to reproduce:
Create a new scene

Project Settings:

  • Allow Static Lighting
  • Global Illumination = None
  • Generate Mesh Distance Fields = False
  • Shadow Map Method = Shadow Map

New Scene:

  • Directional Light → Movable
  • Skylight like described in the following screenshots
  • Bp_Sky_Sphere (which has still not IsSky enabled)
  • LightmassImportanceVolume

World Settings:

  • Volume Lighting Method: Sparse Volume Lighting Samples

Bake lighting!

Result:

  • skylight bounce is not visible on meshes
  • static skylight: clear coat (sphere) has no sky reflection
  • stationary skylight: clear coat has no sky occlusion (when below other meshes)

Legacy Materials - Static Skylight

Substrate - Static Skylight

Legacy Materials - Stationary Skylight

Substrate - Stationary Skylight

The debug view of “Volume Lighting Samples” is broken in all baking modes except when the skylight is static.

The MCP documentation is incomplete, you need to enable manually the toolset registries otherwise the MCP doesn’t do anything.

Well… I reported this in the preview thread, no one replied, and it didn’t get fixed so I may as well double down: Irradiance Field Gather is not usable in its current state:

Does the markerless mocap system only support single cam body capture? I see you can do face and body at the same time, but nothing about multicam body capture. 1 camera is fine if you are not moving around a ton, but you should really have support for multiple cameras to get better 3d space

in 5.8 have no sound, only glitching loudly from time to time, gave me a jumpscare :rofl:

Hi there! Congrats on the release, and thank you so much for your hard work!

Taking this opportunity, I’d like to ask about the Toon Shader BSDF. I understand that it’s still an experimental feature, but we are considering it for a production pipeline.
Could you let us know if there are any critical limitations at this stage that would make it a no-go for large-scale projects?

Also, by default, the shadow appears to be inverted (we’d expect the darker areas to be closer to the feet). Is this a bug of the experimental version, or is it an intended mechanic?

Any insight would be greatly appreciated!

Great! There is tutorial how to setup Mesh Terrain? It Loads 1 minute for me while Landscape load instant at same level size 16K.

I shouldn’t have to say this, since land and water are the 2 most basic things in a game. But the Water plugin and the Advanced Water plugin do NOT work with Mesh Terrain. We built a 30k terrain and the ocean has no under water effects anymore. Also there are no Modifiers for Rivers or Lakes so they can properly affect the terrain in Mesh Terrain Mode. And lastly Shallow water simulation from the Advanced Water plugin does nothing.

Nanite Skeletal Meshes seem broken with hardware raytracing? Is anyone else having this issue
Tried in a test scene and it worked for Instanced Skeletal Meshes but not regular.
Also something is strange with the screen traces and too.

I also found it with Nanite enabled skinned meshes just don’t show up in the lumen scene at all.
Am I missing something or is this broken?

Iris is in Production Ready in this release, can i use it in production game? UE5 will not update, the 5.8 maybe the last relase for UE5, but the Iris is not in Production state, what can i do when i descide which replication system i should use, replicationgraph or Iris.

I feel like saying that “5.8 is the last planned major Unreal Engine 5 release” feels like the wrong call, IMO. Mostly because there are still graphics optimization issues within the engine as it is and a variety of features that are still either experimental or beta. I think you guys should be focusing on getting as many features into stable status rather than just going all-in on UE6. You guys literally just released Substrate NPR Shading as experimental, for example, and even built-in plugins like CommonUI aren’t marked as production-ready. It does not exactly raise developer confidence when they’re not expected to see any further optimizations or notable stability improvements to useful features for at least two years.

Totally agree.

Saying that UE 5.8 is the last planned major Unreal Engine 5 release feels like leaving UE5 unfinished. Many developers are not asking for a bigger engine, a new generation, or another wave of experimental features. We are asking for the current UE5 generation to be finished and optimized.

The main problems are very clear:

  • Many important UE5 features are still Experimental, Beta, or not realistically production-ready for many projects.
  • UE 5.8 also introduces major new systems such as Mesh Terrain, but Mesh Terrain is Experimental. If UE 5.8 is the final major UE5 release, then developers may be left with important UE5-era features that exist in the engine, but do not have a clear path to becoming production-ready inside UE5.
  • UE5 still has real performance concerns across many types of projects. UE 5.8 includes important performance work, and that is appreciated. But developers need predictable real-world performance across actual migrated projects, large worlds, production content, and normal development workflows — not only selected benchmark scenarios.

For many teams, especially game developers, UE6 is not the practical answer right now. We need a stronger UE5.

A focused UE 5.9 would be extremely valuable if it were positioned not as a feature-expansion release, but as a stabilization and production-readiness release:

  • Improve performance across real projects.
  • Fix major regressions.
  • Move mature Experimental/Beta features to Production-Ready status where possible.
  • Give developers a final, reliable UE5 version that can be trusted for shipping games over the next several years.

The concern is the gap. If UE 5.8 is the last planned major UE5 release, and UE6 Early Access is still targeted for the end of 2027, with the full UE6 release coming later, developers may be left for years in an awkward position: UE5 is the engine we are building and shipping with today, but many powerful UE5 systems may remain unfinished, experimental, unclear, or risky for production.

If UE 5.8 were already fully stable, highly optimized, and most core features were production-ready, this would be much easier to accept. But that is not where many developers feel UE5 is today.

Please reconsider and commit to at least one more major UE5 release — UE 5.9 — focused entirely on performance, stability, regressions, production-readiness, and maturing the systems already introduced in UE5.

UE5 does not need to get bigger. It needs to get finished.

100% agree with Ocean above. Also, translucency support for Nanite was recently added to the UE5 main branch and it would be a crying shame if we had to wait for UE6 just to get that, amongst other improvements.

We’re not asking for more big features (we’ve got way more than enough of those already), we just need UE5 to finally feel like a properly polished engine when it’s felt so underbaked since its initial release. There are good reasons why UE5 doesn’t have the best reputation outside of the dedicated developer community right now.

Thanks for the feedback. We currently only support single camera. So favouring ease of capture over needing a more complex synchronised camera setup. This means you aren’t tied to any specific capture hardware or software and can use a huge range of different systems in different environments (e.g. underwater with an action cam). This also means you can use previously captured video if you have existing reference video libraries you’ve built up.
