Can see through a ceiling from "dome" #19

It's relying on vis apparently. With |
There are other maps doing this as well. One example is https://github.com/Masmblr/map-jota_src at One could argue that the parts hidden by the sky are map deficiencies. After all, this must not happen in euclidean space. atcs, for example, erects two huge structures mainly for this reason. Nevertheless, I have wondered on occasion: is there a method to hide such rooms in some shader? Or can cleverly placed vis hints do it? If we cannot find any method to make this room invisible, I see no other way than to either lower the height of the dome's ceiling, or to add nontransparent surfaces on top of the room we can look into. |

Many maps suffer from this, uncreation has some of it (obvious), arachnid2 too (hard to spot). This is due to the skybox mechanism being as fast as it is naïve: the game first paints the sky, then paints anything else (even if the sky surface is in front of it). This is true since forever, tremulous/quake3 suffered from this. Of course it's a map bug since there can't be an hidden room behind the sky in real life, without an actual wall hidingit. This feature by @VReaperV is meant to fix that: See also: |
Indeed, there is no such thing as skybox concealing things, things not rendered are just things excluded by the vis. |

Could it have been the case in the past that the skybox was hiding the geometry behind it? I was certainly up in the dome many times during testing and I never noticed this.
fwiw, I considered there to be some (desert) landscape right around the dome and the hangar exit, with everything else being underground. |
That would probably be the easiest fix right now. Put a sand patch mesh there and call it a day. |

I checked Unvanquished 0.49 and the bug was already there, so this was not caused by recent sky changes. |

Yes, it's super old, there are old threads around about it:
For archaeologist, it was linked there: Unvanquished/Unvanquished#112 |

Funny to see that on the exact same hardware, the new renderer is now able to render the map, a bit slower on same resolution though:
With lower resolution it's more acceptable:
The good news is that the elevator (the vertical lines on the right on screenshot from 2012) is now out of vis thanks to some vis optimizations having been done in the map since that time. |
From this location there is, geometrically speaking, a line of sight to many other rooms, as can be seen by turning on the material system. But the other ones are concealed by the skybox while this one isn't.
