I can confirm this issue but I can't really add anything to the discussion other than, this is not working :|

So this is funny.

KSP has never used two intensities. It has two seperate lights, but the intensity of the scaled space light is assigned to the local space light every frame. Back when I wrote Kopernicus star code, I copied the behaviour from KSP's original code, but I didn't notice this. That means, the local space intensity from the config, even when it still was a single number, got never used. Oh well.

Anyway, I fixed this, and the IVAIntensityCurve with bdfc343

I have also noticed that the IVA color doesn't seem to affect the IVA of vessels

both the small preview in the lower right and the IVA view (default hotkey = [C]) always have white light

Thanks for the response. So with this fix you've made, will IntensityCurve actually work now? Also, what are the distance units in IntensityCurve and IVAIntensityCurve? I know that ScaledIntensityCurve uses km/6000, but I've heard IntensityCurve might be just kilometers, and I don't know anything about IVAIntensityCurve. Can you verify the correct units?

It will work and use kilometers

Thanks. Are the IVA units kilometers also?

Yes

Oops, I just realized I made a mistake. ScaledIntensityCurve uses meters/6000, or km/6. I think IntensityCurve and IVAIntensityCurve are suppose to use meters, not kilometers. Is that right?
