Everything is pitch black until you light it up
I'm sure this might be an issue that would plague something like space exploration too but in the case of warptorio 2 it turns to bright daylight again as soon as you warp to another planet. https://media.discordapp.net/attachments/284326290759221248/774469456851238932/unknown.png?width=1204&height=677
Thanks for this feedback. I need to think about which surfaces it should apply for... There may be some exceptions where people don't want it.
I suppose said exceptions would be surfaces that are meant to act as inside a building...so perhaps if there is a way to check if there are out of world tiles that could be a way of checking though I am not sure how viable that is.
