Some thoughts
Current weatherFX scripts, like Sol, are made to look good with the known Post Processing. They are
balanced to static exposure. This makes things very easy to add new features, but makes it very
complicated later. In the current state of AC/CSP, we have all those wanted things like night
sceneries with additional lights. But to show those things, we made adaption after adaption, to let it
look ok for night and day.
Now, we lower the CSP lights to have them at the right level at day. This works for most of the tracks.
But what if we have tunnels at a track? In a tunnel, the ambient light is nearly 0. So CSP lights should
be fully evolved, but we have lowered them at day. So we need the next adaption. If a car drives into
a tunnel, we need to raise those lights again.
That’s where Pure changes the fundamental things. In Pure there are no lights adjustments anymore.
This is possible, because sunlight and ambient light is much stronger and therefore CSP lights are
much weaker at day.
But now we need to adjust the exposure, what is a natural behavior! In the real world we must adapt
to different light too. So for daytimes, the exposure is much lower, than in twilight and night times.
Due to a better handling of Auto-Exposure (AE) in newer CSP build, we can use AE much better than
before. I achieved a very well working AE control for Pure.
In the picture below, you see the tunnel dilemma. If the car is not yet in the tunnel, lights are
lowered. In Pure, the tunnel lights are active, but much lower, because of the bright sunlight outside.

Comparisons
To show you the differences between Pure and Sol, here are some comparisons of Sol with static
exposure and Pure (dynamic exposure). The track lights are permanently active!
