1. Backrooms Yellow Room Add-on

※ When built above ground, the add-on blocks may let a small amount of light pass through, making the inside of the building slightly brighter.

If you want to create a completely dark room, we recommend building it inside another structure or underground.

※ If you want to place an entity-based add-on perfectly straight in your world, please use the /summon command.

Use the following command:

/summon nyakoppi:<ID of the add-on you want to summon> ~ ~ ~

After ~ ~ ~ (half-width tildes), add a space followed by 90, 180, or 270 to find the direction that best matches your build.

(The ID is the block/add-on name displayed in your inventory or hotbar.)
