The best fuel depends on where you are in the game.
Early game, before you have any farms beyond iron: anything you can burn. Logs, coal, charcoal. You’re unlikely to be doing any serious smelting jobs.
Mid game: Blaze rods (since you’ll likely have a blaze farm), possibly bamboo except you need ~82 bamboo plants per furnace to keep it permanently fueled (164 plants for smokers/blast furnaces since they burn twice as fast).
Late game: Coal blocks (since you’ll probably have a wither skeleton farm). However, that’s not automated. Once the crafter is implemented, the best fuel source will be kelp blocks - without question. You only need ~22 kelp plants per furnace to smelt without ever stopping, fully automated.
Just another reason why you should never, ever pay for a first party server. Find a 3rd party host. Also install the No Chat Reports mod.
Stop supporting this bullshit
Mobs only spawn at light level 0, so any amount of light will block spawning. You need a completely dark room.
The correct Minecraft wiki is https://minecraft.wiki/
The community voted to leave Fandom a while back; the Fandom wiki is deprecated and useless now. It’s only up because Fandom doesn’t allow you to delete wikis.
Backups backups backups. Always make backups.
And remember the rule of backups: 2 is 1 and 1 is none. Things will eventually break, always. Keep multiple backups, on physically separate devices/drives.
Whether it’s with Distant Horizons or legit, long render distances are really ruined by lack of shaders. It’s either DH or C2ME that expands how high you can set the real render distance, but I can set it up to 128 without losing shaders. Looks amazing, but it drops to about 6 fps once it’s loaded past a ~64 chunk radius with an RTX 3070.
The efficiency and computing power aren’t quite there yet, but I think within the next few years we’ll be able to natively run shaders on 100+ render distance using mid-range hardware.
