^^ If the above "quick and dirty sample" is meant in answer to my previous query then I think you misunderstood what I was getting at?
I was suggesting ignoring the uppermost vertical flats altogether by interpreting them as a slightly concave ceiling that arches behind
the curving parts just above the lighting alcove that runs around the bridge (and anchoring to it somewhere behind there).
This way, the indirect lighting comes from the gap between the curved ceiling and the curvy parts below, and reflects off the curved ceiling. This shouldn’t create any “hotspots” should it? Because that’s kinda the point of indirect lighting, it would diffuse evenly over the light grey curved ceiling?
Anywho, I know this isn’t exactly what we see in the screencaps above, but I just thought it might look kinda Kewel, and might even work?
