With PCG, it’s now possible to make manual edits on top of procedurally generated content without breaking the proceduralism, so you can art direct the system’s results while continuing to adjust upstream parameters.
There’s also new support for complex attribute types—including arrays, structures, sets, and maps—as well as new example PCG graphs designed for spatial operations. Together, these features make it possible to generate elements such as buildings, city streets, and much more.
Control Rig Physics moves to Beta, featuring enhancements for both riggers and animators. It’s great for anything from fully dynamic ragdoll animation, such as a character falling down stairs, to subtle secondary motion, such as jiggling flesh.
Physics rigs can now be modular, enabling you to use them with your own rigs. This also means you can layer the physics over existing animation, and keyframe its weighting to precisely control its influence over time.
In addition to Control Rig Physics, which is ideal for cinematics, we’ve introduced Control Rig Dynamics, a new particle-based solver for runtime use that evaluates at five times the speed of the original solver, enabling you to trade off accuracy for real-time performance.
An Experimental new Fog Screen Space Scattering (FSSS) feature is now available on Volumetric Fog and Local Fog Volumes. FSSS simulates multiple light scattering, making dense fog, smoke, and dust appear blurrier and more integrated with the scene for increased realism.
For those looking to mimic 2D, stylized, or hand-drawn anime and cartoon styles, UE 5.8 introduces an Experimental new Toon Shader, built on the Substrate framework. The new shading model supports the full range of UE5 target platforms.
Iterate physics assets faster
Dataflow—Unreal Engine’s node-based system for the procedural generation of physics-based assets—is now Production-Ready, with a slew of enhancements.
In this release, new features for the Dataflow Editor framework include improved graph evaluation, enhanced UI and UX, rich rendering support for most data types, and more.
One of Dataflow’s most exciting applications is for use with Chaos Destruction. With Dataflow, you can implement instant, nondestructive changes, making iteration much faster and more flexible.
Chaos Cloth is also now Production-Ready. We’ve migrated the cloth authoring pipeline to a new Dataflow-based Cloth Panel Editor, bringing closer alignment with panel-driven clothing workflows.
Speed up mobile workflows
Unreal Engine 5.8 brings improved onboarding and faster iteration for mobile developers.
We’ve automated the process of setting up a workstation for Android development, making it faster and easier to get started. That goes hand in hand with extensively updated documentation.
With the updated Unreal Engine Remote application, you can preview, test, and iterate on mobile input—including touch controls and gestures—without building or deploying to a physical device.
Platform Preview also now more closely matches the visual output of the target device, so you can more accurately preview the platform within the editor and iterate on visual aspects of your game without making a build.
Finally, Android developers can look forward to accelerated cook times.
We’ve implemented an Experimental MCP (Model Context Protocol) plugin for Unreal Engine. The open standard plugin enables LLM systems—you can use any model you want—to connect to and understand both the engine and your project. You can then use them to help you build assets and systems; extend engine functionality; perform testing and optimization tasks; and more.
The plugin ships with built-in exposure to many core systems, including Blueprints, assets, levels, materials, meshes, and many more; developers can easily extend it with their own functionality.
