Nobody has beaten anyone - it just needed someone to look into this. And I guess you made me curious enough. I could not have done any of this without KNG or DJ work or the others help (and you btw cos you insisted) and quite a lot of guessing...
the mod will come out later today (not by me) and I have already made a script version too.
This like most of good modding was really a collaborative effort.
By collaboration I mean, we, who came late to the party, can just build on other people’s work - wkit, the scripthook and kbowlwdge others have acquired... that’s what I mean with collaborative effort.
Do the Masters of lights and shadows know where the fake light from Windows is coming from at night (in Novigrad)? Interiors are significantly dimmer than fake window lights. I found a shader that I think is responsible for it, but shader settings are usually over-written by material and FX, which I can't find. Maybe window meshes have them - have no idea, would be great to know.
