Epic Games has officially released Unreal Engine 5.7. The update expands major systems across rendering, procedural content, materials, animation, and virtual production. It also introduces an in-Editor AI Assistant. Several features, including the Nanite Foliage rendering system, remain Experimental, while others, most notably the PCG framework and Substrate materials, are now designated production-ready. If you think “Didn’t you tell me all of this already?”: We had a Preview-News for the Preview and Teasers.

Procedural Content Generation (PCG) ready for production

Epic now considers the PCG framework suitable for use in final projects. The system allows artists to populate large environments procedurally, introduce variety, and automate level construction. Unreal Engine 5.7 adds a dedicated PCG Editor Mode, performance optimisations for GPU compute tasks, and a Procedural Vegetation Editor (PVE) for foliage placement. While PCG itself is stable, the PVE remains Experimental. Epic recommends verifying runtime performance and scalability before adoption in production environments.

Nanite Foliage enters testing

Nanite Foliage introduces a new geometry rendering pipeline for dense, animated vegetation in open-world environments. It combines Nanite Assemblies, Nanite Skinning, and Nanite Voxels to balance geometric detail with runtime efficiency. Epic lists the entire system as Experimental. Studios considering it for production should expect incomplete support for physics, collisions, and wind animation, and should validate performance on target hardware.

Substrate materials: modular and physically accurate

The Substrate framework for modular material authoring and rendering has graduated to production-ready status. It enables layering of physically accurate material types such as clear coat, metal, cloth, and skin, producing more realistic composite surfaces.

For material and look-dev teams, Substrate now replaces earlier shading models in complex asset pipelines. Epic recommends migrating projects incrementally and benchmarking shaders to ensure compatibility and consistency across devices.

Animation and virtual-production improvements

Unreal Engine 5.7 extends its animation toolkit with an overhauled Animation Mode, improved IK Retargeter and Skeletal Editor, and a new Dependency View for visualising control hierarchies.

For virtual-production users, the engine adds a Live Link Broadcast Component, allowing Unreal itself to act as a live animation source on-set. Composure, Unreal’s integrated real-time compositor, has been upgraded for improved handling of shadows, reflections, and colour accuracy during LED volume shoots. Incremental Cooking enters Beta, promising faster asset iteration for large virtual-production projects, though Epic cautions against immediate production use.

AI Assistant built into the Editor

A new AI Assistant now lives directly within the Unreal Editor. Users can ask technical questions, request code snippets in C++, or receive step-by-step instructions without leaving the viewport. The tool is designed to reduce context switching but is not intended to replace documentation or verified workflows. Its long-term reliability in multi-user pipelines remains untested, and Epic has not disclosed details about data handling or privacy.

Extended MetaHuman and cross-platform updates

The MetaHuman Creator plugin now runs on Linux and macOS, expanding platform support beyond Windows. Additional scripting APIs enhance automation and integration for character pipelines.

Here’s more about the Hairstyle generator.

Rendering, audio, and mobile improvements

Rendering updates include support for Android 15, new “Geometry Inspection” viewport modes for surface analysis, and expanded anti-aliasing and shadowing options. Nanite continues to gain broader coverage across rendering passes. Audio workflows benefit from “Audio Insights” (Beta), enhanced subtitle support, and updates to the waveform editor. These features target real-time review and iteration efficiency rather than final mixdown.

Caveats and production considerations

Despite multiple “production-ready” designations, Epic’s documentation lists numerous features as Beta or Experimental. Nanite Foliage, the Procedural Vegetation Editor, and MegaLights are explicitly unfinished. Documentation for several systems remains incomplete, and large projects upgrading from earlier versions will require shader recompilation and plugin verification. Studios are advised to test workflows in parallel, evaluate GPU and CPU loads, and confirm asset compatibility before upgrading live projects.

PCG Hits Production Readiness

Unreal Engine 5.7 Preview is now available free via the Epic Games Launcher, GitHub, and Linux.
The headline feature: the Procedural Content Generation Framework (PCG) is now officially marked Production-Ready. Epic reports that GPU and game-thread optimizations have pushed PCG to nearly twice the performance vs UE 5.5. Parameter overrides for GPU nodes allow dynamic tuning; scaling and improvements make the GPU Compute path (including FastGeo use) more viable across platforms.
A new PCG editor mode adds spline drawing, paint, and volume tools. PCG Graphs may now run as standalone flows. Epic emphasises, however, that PCG is still under active development (i.e. not final in every respect).

Procedural Vegetation: Grow Inside the Editor

An Experimental Procedural Vegetation Editor plugin arrives, built on PCG nodes. It lets users grow, sculpt, and vary Nanite-ready foliage in real time inside Unreal, without hopping to external tools. You can adjust tree structure under gravity, scale branches/leaves, swap models, and export as static or skeletal meshes.
Epic plans new Quixel Megaplants assets timed to the full 5.7 launch to support this workflow.

Nanite Foliage: Dense, Animated, and Experimental

Nanite Foliage is shipping as Experimental. It’s composed of three linked systems: Nanite Assemblies (for variation/instancing), Nanite Skinning (for animation like wind), and Nanite Voxel (for preserving detail at all distances).

Epic claims these allow rendering and animating dense foliage at 60 fps on current gen hardware, while managing memory, variation cost, and visual fidelity.

Lighting Revamp via MegaLights

MegaLights advances to Beta. It now supports directional lights, Niagara particle lighting, translucency lighting, and hair grooms.
New controls let devs tune resolution scale and update rates. Noise reduction is improved to reduce visual artifacts while keeping performance manageable.

Substrate Materials Graduate to Production

Substrate materials exit beta and enter full production-readiness. This modular system replaces legacy fixed shading models with layered, flexible materials.
Unreal now supports both Adaptive GBuffer (for complex, per-pixel topology and layered closures) and Blendable GBuffer (for broader platform coverage). Developers can combine layers like metal, cloth, clear coat, and skin with physically accurate blending under the same framework.

Animation & Rigging Enhancements

UE 5.7 continues and extends 5.6’s trajectory. New Selection Sets allow animators to define groups of controls easily and share them across teams—reducing dependence on bespoke GUI Pickers.
The Animation Mode UI has been refactored: tools may be minimized to free up viewport space. The Constraint UX window merges Space, Constraints, and Snapper tools under one symbol for unified access.

On the rigging side (Experimental), Unreal adds sculpting and blend shape editing in-engine. You can create or adjust morph targets, bones, and skin weights without leaving Unreal. Physics World Collisions strengthen real-world interactions, and a new Dependency View visualises how rig data flows, aiding debugging and optimization.

Epic Developer Assistant: UI, But Not Yet Active

The UI for the forthcoming Epic Developer Assistant is included in the preview, but functionality will only activate with the full 5.7 release. The planned assistant aims to deliver context-aware help, code generation (C++) and guidance within the editor.
While it’s not fully in the preview, the tool is operational on the Epic Developer Community for Unreal Engine 5.6 users.

MetaHuman 5.7: Cross-OS, Smarter, Fancier Hair

In 5.7 Preview, MetaHuman gains important upgrades. The MetaHuman Creator plugin now supports Linux and macOS, and almost all editing/assembly operations are exposed via Python and Blueprint APIs.
Body conforming becomes pose-agnostic, using UV-space vertex correspondence for consistent rig deformation. Improvements include better calibration for stereo-camera capture data and more expressive hair control (joint-based deformation, paint-based guide control). Additional mood overrides enhance audio-driven animations.
Epic cautions that some issues remain in Preview — crashes on reassembly, texture blackouts with Substrate, blending errors in body presets, and limitations in UEFN export support. Developers are encouraged to test in separate project copies.

When Will Full 5.7 Arrive?

Epic maintains a public Unreal Engine roadmap via ProductBoard. portal.productboard.com The roadmap includes a “Forward-Looking” section marked for UE 5.7 However, Epic has not publicly committed to a firm release date for 5.7 (or its full stability). The roadmap items transition to concrete features only as the version approaches launch. Until Epic issues a formal release schedule, we only know that 5.7 remains in active development.

Early Access Means Early Risk

Epic reminds users that Preview builds are not fully quality-tested and remain unstable. Projects should be duplicated before testing. Avoid converting production assets or codebases until the final release.

Availability: Unreal Engine 5.7 Preview is free. Download via the Epic Games Launcher, GitHub, or build for Linux.

Reminder: Always validate preview features in controlled tests before integrating into production pipelines.
