These HDRIs are not AI-generated and are not upscaled. Every environment was rendered directly at the full 16384 × 8192 resolution.

Every panorama is rendered at native 16K resolution — 16384 × 8192 — in a full 2:1 equirectangular format, making the environments ideal for cinematic backgrounds, skyboxes, reflections, space scenes and image-based lighting workflows.

The pack includes a ready-to-use Unreal Engine 5 project, while the original high-resolution EXR and HDR files are supplied as Additional Files, allowing the environments to be used outside Unreal Engine in other real-time engines, DCC applications and offline rendering pipelines.
