Yes, as @simsontherope and I discussed on the forums, I am not able to duplicate the issue. In my game (also 64 bit and maxed settings), the light is flowing down from one level to another just fine (you can see our discussion and images here). It would be helpful if others who are experiencing the issue could post their specs.
And just to note, my graphics card is a NVidia GTX 980 Ti.
Regarding the triangular shadows glitch reported in the index, it crops up fairly frequently in builds I've seen, but if the team wants one in particular to examine, the build I've been double-checking after patches is Windenburg Manor by anja_gersti. You'll see the shadows in the 3rd floor bedroom.
I have now been able to duplicate the lighting issue described by @simsontherope and will add it to the index. Interior lighting in open stories does not flow down to lower levels if a roof fully covers the area, even though a ceiling/flooring is in place between the roof and structure. A partial roof or no roof will not cause the problem, only a complete roof or roofs covering the area.
Another lighting issue to report: light shines in a line through bottom of a half wall placed above (and joining to) wall below and shows a weird cutoff between them that you wouldn't normally expect to see:
Added another issue to the index: certain lights cause large, blocky shadows on exterior walls at night:
At first, I thought the shadow from this particular light might be caused in part by the planters, but rotating the light had no effect:
Lights with the glitch include Georgina Outdoor Lampost with Double Hanging Planter, Dual Lit Ole Fashioned Lamppost with Planter, Great Attractors Street Lamps, and A Modern Illumination.
