Last April, Unreal Engine added beta support for ray tracing and path tracing, letting developers get the most out of DirectX 12 and DirectX Raytracing (DXR). Since then, we’ve seen teams of all sizes achieve incredible results, adding dynamic global illumination, pixel perfect reflections, and physically accurate refractions to their applications.
Unreal Engine’s real-time ray tracing features have continued to evolve, culminating in today’s release of UE4.23.
Ray tracing in UE4.23 brings improved stability and performance, and supports additional materials and geometry types, including landscape geometry, instanced static meshes, procedural meshes, and Niagara sprite particles. Denoiser and ray traced global illumination (RTGI) quality has improved. Support has been improved for multi-bounce Ray Traced Refflections (RTR) by falling back to Reflection Captures in the scene.
