The Reflections tech demo was created by Epic Games in collaboration with ILMxLAB and NVIDIA. Reflections offers a sneak peek at gaming's cinematic future with a stunning, witty demo that showcases ray-traced reflections, ray-traced area light shadows, ray-traced ambient occlusion for characters and NVIDIA DLSS technology.

Epic built the computer-generated (CG) scene using assets from Lucasfilm's Star Wars: The Last Jedi featuring Captain Phasma, clad in her distinctive armor of salvaged chromium, and two stormtroopers who run into her on an elevator on the First Order ship. In the tech demo, lighting is moved around the scene interactively, as the ray-traced effects including shadows and photorealistic reflections render in real time. The stunning image quality of highly reflective surfaces and soft shadows has never before been achieved at such a high level of image fidelity in Unreal Engine.

Next-generation rendering features shown in the demo include:

• Textured area lights
• Ray-traced area light shadows
• Ray-traced reflections
• Ray-traced ambient occlusion
• Cinematic depth of field (DOF)
• NVIDIA GameWorks ray tracing denoising

Requirements

• OS: Windows 10 1809 (Windows 10 October 2018 Update)
• NVIDIA GPU with DXR support
• NVIDIA Driver 416.25 or newer (GTX 10-series and GTX 16-series requires 425.26 or newer)

To run the demo, launch ElevatorDemo.exe. This will automatically select the appropriate resolution based on the current desktop resolution. The supported resolutions are 3840x2160, 2560x1440 and 1920x1080. The desktop resolution must be at least 1920x1080 to run the demo. Note that the effective 'desktop resolution' is the desktop resolution divided by the Scaling factor. For example, at 3840x2160 with Scaling set to 150% the effective resolution is 2560x1440, which will prevent from running at 3840x2160.

Keyboard bindings:

• F1: toggle display of text with current resolution and FPS (disabled by default)
• P: restart cinematic
• Escape: exit
