Deco Rocks
by AlexStar
Deco Rocks adds five stone types with more than 100 decorative blocks, plus ore generation and ruin structures that players can explore for them.
What it does
The mod expands the block palette with five new stone families, and each set brings together more than 100 decorative blocks in total. Builders get new materials for walls, floors and rooms, and the blocks are obtained through ordinary survival mining, so they do not need creative mode. Smelting one of the stone types also yields an iron nugget, which gives the material a use beyond decoration.
The stones generate in the world according to where each one turns up. Soft rock sits near sea level and shows up in plains, deserts and savannas. A cold variety appears in snowy biomes, while another is found only in cherry groves and jungles. One stone forms only as a transition layer between regular stone and deepslate, and deepslate mines hold a further type. Each stone also has its own ruin structure, so exploring a biome can reveal these block-related remains.
The mod runs on NeoForge 1.21.8 only, and it is released under the MIT License without being open source. Client and server both need it, so every player on a server running Deco Rocks must install it as well.
