Randomosity (being remade)
by flap22
Randomosity is a NeoForge world generation mod for Minecraft 1.21.4 that adds a large set of new stones, ores, building blocks and dimensions to the game.
What it does
New stone types generate in the environments named by the author: Porphyry and a quartzite stone in deserts and badlands, stone that becomes mud cobblestone and mudstone deepslate in swamps and mangroves, and a mold-colored dripstone that can be found in several cave and coastal settings. Diorite moss turns up in lush caves, and indigo gabbro appears in oceans. The stones are meant to be used as building material for many kinds of structures.
The additions extend beyond building blocks. Digitiles, a block with 16 colors that cannot be dyed, come from an old web structure. A redstone emitting block, a spinning top, and an explosive affected by gravity are listed among the planned items. Stibnite and a cutlass are marked as work in progress and available in creative only, while tungsten must be mined with a diamond pickaxe. A new dimension is planned to open through a cobalt gate that is activated with a portal drive, and two biomes are listed as untitled.
The mod is client required and server optional, so players install it and the server may run it for its extra features. It is distributed under All rights reserved, which means the code is not open source. It is published for NeoForge only, with one beta file, 1.0.0 for 1.21.4, released on 2025-09-06.

How it compares
Buildineer is a NeoForge mod for 1.21.1 that runs on client and server, under All rights reserved, so both sides need it. Mosslings is a NeoForge mod for 1.21.1 with the same environment and license. Lawrence's Ambient Fireflies is released under the MIT License for 1.21.5 – 26.2 on Fabric, Forge, NeoForge and Quilt, and a server can run it while players may leave it out. Randomosity differs by staying on NeoForge and 1.21.4 only.
