These renders were created using one of my custom HDR skies, part of a growing 4K HDR library I'm building for Unreal Engine 5.
The goal is to deliver cinematic and realistic skies that are plug-and-play, to help speed up lighting setups for outdoor environments.
The lighting setup here is minimal: just a Directional Light, HDRI Backdrop, and a Skylight.
More skies in development.
