Changing skies in Final Doom?

[Maes]

I vaguely remember that some Final Doom level changed skies during gameplay, although that could just have been a savegame glitch...any relevant info on that?

I don't know/think there's much difference between Doom.exe and Tnt.exe...except the number of demos (doom.exe has 4, tnt.exe has 3), storylines, level names, stuff like that.

The sky is known to be buggy: http://doom.wikia.com/wiki/Sky_never_changes_in_Doom_II
There is no way to set it during gameplay in Vanilla Doom.

...one more reason I hate Doom 2.

Heh, and I always thought it was a feature, because the change was very noticeable in some level where you were supposedly on board of a spaceship or transport (TNT/Plutonis level 12?) and I thought it was some cool feature that activated after you visited a certain part of the level, indicating that the transport had landed or something.
