Walls casting shadows into room even with constructed roof

[Chuck]

Basically what the title says. I have a room, with a roof built on it completely, but i still see the walls casting shadows into the room as the day progresses. Pretty sure the roof isnt made of glass.

[Narrowmind]

It could be the wall isn't fully built yet, but you've given the order that's just not been fulfilled. I've seen it before. It will go away.

I've been having a bit of that in my own game - and it feels especially noticeable during a blood moon (idk if that's just my perception of it though).
Could be a mod issue for all I know, though I haven't tested that myself.

Iv had this happen twice since the dlc. Restarting the game fixes it. Not sure what causes it tho.

[Jaggid Edje]

Do you use any performance enhancement mods? They would be the most likely culprits, I imagine.

(Rocketman includes a tweak to the lighting model, for example, which makes it only update some of it, rather than everything, based on what the mod thinks is actually needed. )

[MadArtillery]

Haven't seen this at all. It definitely sounds like something a performance mod could cause though.

I bet you just made roofed area outdoors (even if it is a room without 1 block of wall it still counts as outdoors), because what you described is happens with roofed areas outdoors, looks weird but apparently it is not a bug

[Mringasa]

I have this happen pretty often. I generally just ignore it because it doesn't do anything other than visually. Using Rocketman, so would not surprise me if that was the issue. Only started happening with the new update, so I imagine something got changed inside the game that needs updated on one of my mods to stop it from happening.

Also noticed this with a room leading to an outer bunker, playing vanilla. Minor bug, I guess.

[Steelfleece]

Not sure for those playing vanilla, but I do know embrasures from various mods don't act as full walls; they don't separate a room from another room or the outdoors.

Its a visual bug in vanilla. If you have a mountain base and a small area isnt under the roof already, sometimes your pawns wont build one right away when its full enclosed. The tiles that are unroofed then start using the unroofed visuals, and when your pawns finally deign to roof it (or you notice and make it a roof area) the visuals stay in the unroofed form.

This has been around since at least 1.3
