We're excited to announce that Unreal Engine 5.3 is now available. This release brings numerous wide-ranging improvements as we continue to expand UE5's functionality and potential for game developers and creators across industries. As well as enhancements to core rendering, developer iteration, and virtual production toolsets, we're introducing Experimental new rendering, animation, and simulation features to give you the opportunity to test extended creative workflows inside UE5—reducing the need to round-trip with external applications.

Refinements to core UE5 rendering features
With this release, we've continued to refine all core UE5 rendering features to address our ongoing goal of making it easier for developers to leverage them at higher quality in games running at 60 FPS on next-gen consoles; the improvements also offer higher-quality results and enhanced performance for linear content creators. Specifically, Nanite has faster performance for masked materials, including foliage, and can represent a greater range of surfaces due to the new Explicit Tangents option, while Lumen with Hardware Ray Tracing has expanded capabilities that include multiple reflection bounces, and delivers faster performance on consoles. Other areas with notable advancements include Virtual Shadow Maps (VSM)—which is now Production-Ready—Temporal Super Resolution (TSR), Hair Grooms, Path Tracing, and Substrate.
