Updated the mod to version 1.1:
The only "new" thing is the reactivation of fog in the Ravager levels.
This was possible due to bead-v's discovery of which byte enables/disables fog rendering on a model. For some more details: Fog in the KotOR games is a one color overlay with increasing opacity in the distance. Now if fog was rendered on a skybox or star backdrop, that backdrop would obviously disappear behind this solid color, which is why there had to be something in the model telling the game whether it receives fog or not. But until yesterday, I didn't know what so the only way to make my added backdrop models not appear as flat grey on the Ravager was to disable the fog entirely. But with bead-v's discovery I could now re-enable the fog while keeping my backdrop models normally visible.
The screenshot shows the view from the Ravager in v1.0 as well as in v1.1. As you can see, there is now a grey overlay on the Ravagers structure while the backdrop is completely visible. On the right, you see what happens when fog is enabled in v1.0... which is obviously not great.
And here's a screenshot from inside the Ravager that shows the improved atmosphere with fog re-enabled.
