Fellow Kerbonaut Krazy1 reported on Forum a possible enhancement for the SkyBox Dimming.
I think I see a new issue... The skybox dims when in low orbit at night (eclipsed) and looking at the planet (which is also in the direction of the sun). It's like you're looking at the sun without the planet blocking the sunlight. I don't think it did this before but maybe I'm wrong.

Check it and implement it if needed.
