Natural Light Levels and Player-made Enclosures

[gilt-kutabe]

Hello!

I’m trying to make a cellar for blue cheese, but keep running into a problem. I dig out the cellar, and make twisty halls until it’s pitch-black (I’m working in the middle of the day). However, once I replace the walls with nicer cellar blocks (mud brick, drystone), it’s bright as day down there. I don’t think it’s a time of day thing - I have a sub cellar dug out of my main cellar, and that one has stayed dark. The difference is, I didn’t replace those walls since I just planned to patch it up once I found out if it would work. So I’m wondering: does the game detect non-natural blocks in an enclosure, decide it’s a player-made structure, and bump up the light levels to make it more convenient for the player? And if it does, does it truly raise the light level (and turn my cheese into cheddar), or is it just visual? I can include screenshots if it would help.

Thanks!

So I dug out all the blocks I put down, filled the cellar back in with normal dirt (simply replacing the walls didn’t do anything), and dug it out exactly the same way I had it before. It is now completely dark in there again, and I get cave music in there. I’d love to decorate down there, so if anyone knows the exact mechanics of what’s going on I’d really like to know, but it seems to be working for now.

Im having the same issue here.. I dug out a room underneath my kitchen. lined it with granite stone..

during the day it is as bright as outside in the room and it's performing badly as a cellar..
