HDR Light Studio defines HDRI map:

A HDRI map (high dynamic range image map) is a digital image file commonly used in 3D computer graphics for image-based lighting. The rectangular photographic image captures a view of a location in all directions from a single viewpoint - where the pixel brightness values in the image are unlimited and match the real-world lighting values.

Blender 2.8 and newer contains a number of HDRi's in it by default for LookDev. I'd like to know how to use them in final renders (EEVEE or Cycles), because quite frankly they appear fantastic.

HDRI doesn't show up in the final render

I've got a problem again. :) My HDRI does show up in the viewport, no matter if it's in renderview oder solid, etc. Unfortunaly, it won't show up in my final render. Since it's the main light, it's just dark.
