Unreal Engine 5.7 builds on the previous release with a strong focus on large, detailed environments and more capable real-time rendering. These are the highlights.
PCG becomes Production-Ready
The Procedural Content Generation framework reached Production-Ready status. The new PCG Editor Mode adds artist-friendly tools such as spline drawing, point painting, and volume creation, all powered by PCG Graphs.
New options for dense foliage
Nanite Foliage arrived as an Experimental system designed to render extremely dense, detailed vegetation more efficiently. The Procedural Vegetation Editor also offers a graph-based way to create vegetation assets inside Unreal.
Substrate reaches Production-Ready
Substrate, Unreal Engine's modular material framework, became Production-Ready. It makes layered material looks—such as automotive paint, cloth, skin, and coated surfaces—more flexible and physically grounded.
MegaLights moves to Beta
MegaLights advanced from Experimental to Beta, allowing scenes to use many more dynamic shadow-casting lights. Epic also improved performance, noise reduction, and support for different lighting situations.
Animation and MetaHuman improvements
The Animation Mode was refactored, Selection Sets were added, and IK Retargeter and skeletal editing workflows improved. MetaHuman workflows gained more scripting and automation options, alongside expanded capture support.
An AI assistant inside the editor
A new in-editor AI assistant can answer Unreal Engine questions, help generate C++ code, and guide users through editor workflows without leaving the application.
