HDRi Lighting Preset HDRi Lighting Preset Scene illuminated by HDRi Sky. The HDRi Sky preset loads a HDRi background and sky - Bear Mountain - and make other settings to make the sky visible. We have been able to use HDRi Skies for lighting in the past, but the new Lighting Preset makes it easy to set one up with a single click. After selecting this preset, you can easily use the HDRi tab to select other skies. See: HDRi Lighting Preset See: HDRi Skies
