Sorry for this late reply.
Just a thought. I wonder whether cockpit lights and constant brightness levels for luminescent markings (regardless
of lighting conditions) could be achieved without major code changes.
I cannot do much, texture wise, with any of the lights.
As far as the constant brightness levels for luminescent markings (regardless of lighting conditions),
You may have noticed that the gauge face markings, luminescent or not, have different different characteristics as to lighting condition,
than the pointers do.
The gauge face markings stay mostly the same color, while the pointers change color kind of drastically.
Now.. Osram made a SHADER tool that artists (better than me) can change this. Maybe I can make the Gauge face markings
react to lighting conditions more than I have them doing, now.
I have only briefly experimented with this Shader stuff, last year, and made some noticeable effect changes,
but I do not yet really know what I am doing!
FIRST! I got to get all the gauges looking better, and calibrated best I can. Then I can start thinking about Shader effects.
Also I wonder whether the Luftwaffe used a different type of luminescence or florescence.
The radio luminescent paint mix that the Germans used was likely not EXACTLY like that used by the English or the Americans, I suspect.
I would expect it to be very similar, so that I shall not differentiate between the two.
Unless you can find an old ex-LW mechanic and/or an old German that actually painted with this radium paint,
like I did with Prem Holdaway, whom was both, but in England,
for a first hand account of what color it was, I'll make them the same.
The difference would likely be minute.
