Epic’s latest Unreal Engine update brings production-ready procedural world building, new rendering and lighting features
Unreal Engine 5.7 is now available, bringing a wide set of updates for teams building large, detailed worlds on current-generation hardware. The release focuses on faster world building, higher fidelity rendering, stronger character tools, and new workflows for virtual production, all wrapped with a new in-editor AI Assistant (I guess this was inevitable) to help users navigate the engine.
The Procedural Content Generation (PCG) framework is now marked Production-Ready. A new PCG Editor Mode adds spline drawing, point painting, and volume tools that connect directly to PCG Graphs, so creators can adjust parameters in real time without coding. PCG GPU compute gets performance optimizations and support for GPU parameter overrides (no word on actual % improvements), while a new Polygon2D data type and related operators make it easier to define areas and splines. Epic also introduces the Procedural Vegetation Editor, an experimental graph-based tool for building vegetation assets, with first-wave Quixel “Megaplants” recipes available through Fab.

On the rendering side, Unreal Engine 5.7 debuts Nanite Foliage as an experimental feature for dense, foliage-heavy scenes (picture above on the left). It uses Nanite Voxels to draw huge numbers of small overlapping elements like tree canopies and ground clutter at stable frame rates, plus Nanite Assemblies and Nanite Skinning to keep storage, memory, and animation costs under control. Substrate, the modular material framework, is now Production-Ready, enabling physically accurate layered materials such as car paint or skin across platforms down to mobile. MegaLights moves into Beta with support for many dynamic shadow-casting lights, better soft shadows, directional light support, shadow-casting Niagara particles, and improved hair shading along with noise and performance tuning.
Unreal Engine 5.7 (what’s new):
- Production-Ready Procedural Content Generation
- PCG Editor Mode
- Procedural Vegetation Editor (Experimental)
- Quixel Megaplants support
- Nanite Foliage (Experimental)
- Substrate material framework (Production-Ready)
- MegaLights (Beta)
- MetaHuman Creator plugin for Linux and macOS
- MetaHuman batch processing via Python/Blueprint
- Live Link Face external-camera support
- Refactored Animation Mode
- Selection Sets
- IK Retargeter updates
- Enhanced Skeletal Editor sculpting and weighting
- Dynamic Constraint Component for props
- Live Link Broadcast Component
- Updated Composure real-time compositing
- In-editor AI Assistant
- New Unreal Editor Home Panel
MetaHuman gains deeper integration. The MetaHuman Creator plugin now supports Linux and macOS, with batch and automated processing of MetaHuman assets through Python or Blueprint. Mesh conforming workflows improve round-tripping with DCC tools, and Live Link Face can now drive real-time facial animation from external cameras attached to iOS or Android devices (I think this is very cool, picture below).
Animation tools get a refactored Animation Mode, Selection Sets for quick rig control selection, an improved IK Retargeter, enhanced Skeletal Editor sculpting and weighting, support for one-way physics collisions for more natural ragdolls, and a new Dependency View to visualize complex Control Rig setups.

Finally, the new AI Assistant i n the Editor offers context-aware help, code generation, and step-by-step guidance, while a refreshed Home Panel centralizes access to tutorials, documentation, community resources, and a guided “Getting Started” sample.
Of course this is interesting to developers, gamers may not see much fruit from these announcements soon, like we typically observe with previous releases. But in case you are eager to learn more, everything is explained in the video and article below.
