Didn’t skip anything, if fact will probably rewatch the Eevee and probably a few YouTube vids for variation sake. (edit). Having rested a bit , I went back to the lesson with a clearer head. I now believe I’ve grokked the beginning of the video. I’ll pledge now never to use HDRIs (for indoors at least) and Mesh lights to light an Eevee scene. Just lamps and some well spaced probes. 🙂
