Real-Time Ray Tracing Has Come to Unreal Engine with the Release of UE4.22

AI-Generated Summary

  • Unreal Engine 4.22 introduces early access support for a real-time ray tracer and path tracer optimized for DXR and NVIDIA RTX series GPUs.
  • The real-time ray tracer provides soft area shadowing for Directional, Point, Spot, and Rect light types, accurate reflections for objects in and outside the camera frustum, and soft ambient occlusion to ground objects in the scene.
  • It also delivers physically correct refraction and reflection results for translucent surfaces and indirect lighting from dynamic global illumination from light sources.
  • NVIDIA, Microsoft, and Epic Games launched the DXR Spotlight Contest for game developers and content creators to build tech demos using Unreal Engine 4.22 with DirectX 12 and DirectX Raytracing.
