NVIDIA has recently released its RTXGI Unreal Engine 4 plugin on the UE Marketplace, allowing for much easier integration into game projects.

RTXGI UE4 plugin v1.1.40 is now available on the Unreal Engine Marketplace! This binary plugin can be dropped directly into vanilla UE4.27. No code patches or engine (re)compilation required. Works with all RT capable GPUs. Enjoy!https://t.co/Jx96lR0UiB pic.twitter.com/2VxPwtRMao

Here’s the official overview of RTXGI.

RTXGI is already used in several released games, such as Metro Exodus and Metro Exodus Enhanced Edition, Cyberpunk 2077, Control, Minecraft RTX, Quake II RTX, Escape from Naraka, LEGO Builder’s Journey, The Persistence, Justice, Moonlight Blade, Fortnite, Xuan-Yuan Sword VII, Enlisted, Five Nights at Freddy’s: Security Breach, The Fabled Woods, and other upcoming titles like Dying Light 2, Bright Memory: Infinite, Loopmancer, Faith of Danschant: Hereafter, and Icarus.

Features:

No UVs. No Light Baking. No Light Leaks.

  • Dramatically speed up iteration time with real-time ray traced lighting. No more obsessing over light probe positioning; no light or shadow leaking

Infinite Bounce Lighting in Real Time

  • RTXGI’s probe-based data structure temporally accumulates and filters irradiance and distance information in real time, creating a high quality infinite-bounce cache with visibility information

Content Creation at the Speed of Light

  • Artists get instant results in-editor or in-game. Move an object or a light and global illumination updates in real time

Available for any DXR Capable GPU

  • RTXGI’s scalable design gives you the control to decide when and where maximize performance or image quality

Still, NVIDIA’s goal is to further increase the adoption of RTXGI even among indie developers. To that end, they’ve published a plethora of video guides to help with the implementation of the ray-traced global illumination technology. We’ve embedded them below for anyone interested.
