Strange thing happening with a test mission using BlackWolf's installation with lightning effect.
The lightning effect is basically multiple sections of a tubular model aligned with the ring-formed tunnel. Those models are docked with the station, stealthed, and their health is set to 1% to make them flicker with damage lightning.
With a regular build,
everything works nicely. But, with the shadow build enabled, every time the player ship is either close enough to the lightnings, or directly looking at them, everything goes sort of dark. Not completely dark - the station model is visible. Background skybox is semi-visible. HUD is visible -
as a black silhouette. The lightnings are ALSO visible as black silhouettes against the illuminated sides of the model.
As I turn away from the station and get some distance, rendering gets back to normal.
But wait, it gets weirder still!
When I enabled cheats and destroyed the station while looking at it (things were dark), but I could see my HUD and the station), everything went permanently dark.
And with permanent, I mean that there was nothing but black on the screen.
I hit F2, the game clearly went to the menu (I could hear mouse movements trigger sound effects of the menu), but everything stayed black.
I went back to mission, still black. Hit ESC and Y to quit mission - went back to mainhall which was black. Hit Esc and Y again to quit game, and the blackness disappeared.
Now, I don't know if all this was related to BW's model, the damage lightning in mission doing something bad to the shadow mapping, or something else altogether but it was rather strange anyways, especially how the blackness persisted even after quitting the mission.
EDIT: It's definitely the damage lightning hackish effect thingy. Model itself works fine.
