For me, it will be interesting to begin with lighting philosophy (lamps, sky, hdr, light shader)
Next, the materials; some parameters have no explanation for me (u&v exponent, Sigma...)
And you can give some tips on the specific workflow with lux : how to see textures, how to connect shader nodes...)
I've been interested to see how you configure the scene settings and process settings because I encounter lot of problems (strange folder creations on scene export path, errors with export batch - we've seen that before
...and portals, scenes scale.....
