Backrooms Resources [ALPHA]

by Redomel

Backrooms Resources adds a backroom dimension for NeoForge 1.21.1, with entities, blocks and a day and night cycle tied to its lamps.

NeoForgeClient or server, optionalAll rights reserved1.21.1

What it does

Players who enter the backroom dimension find room generation with wallpaper in several variations, concrete in a range of colors, yellow grass, and ceiling tiles with fluorescent lamps. The lamps change brightness as the in-game day turns to night, so the same rooms look different at each time of day.

The mod also adds entities that copy the skin of a player, along with the blocks that build the dimension. Geckolib is required, so it must be installed next to Backrooms Resources. The mod is NeoForge only and runs for 1.21.1. Either side can run it, and neither needs it. The mod is released under All rights reserved and is not open source.

Key features

  1. Backroom dimension

    A separate dimension filled with generated rooms, built from the blocks and entities the mod adds.

  2. Wallpaper and concrete

    Hard wallpaper comes in several variations, and concrete comes in a range of colors for walls and floors.

  3. Day and night lamps

    Fluorescent lamps on the ceiling tiles change with the in-game day, so the lighting of the rooms follows the time of day.

  4. Copied-skin entities

    Entities that take on the skin of a player appear in the dimension.
