All previews for HDRI Sky domes were rendered in Blender 2.8. Scene setup was very easy: huge plane mesh was added for the floor and Checker Texture inserted into material's Base Color input.

All HDRi Maps were loaded as a sequence for Environment Texture, so all 95 HDRI Skydomes could be rendered in Cycles at once as an animation.
