Polymerized Nether Ores
by Relism
Polymerized Nether Ores, a Fabric server mod, generates Nether versions of vanilla and modded ores in the world.
What it does
On a server running the mod, ores from vanilla and from other mods are given Nether variants during world generation. Block interactions stay as they are: Fortune, Silk Touch, and any smelting or other processing added by other mods behave the same on the Nether versions as on the originals. Players who join with a standard vanilla client still see the custom ores, because the textures are delivered through a resource pack.
The server requires Polymer, which generates the textures on the client side, and Fabric API. After the first start, the server generates its configuration files, and the mod sets the required options to enabled. When a player joins, they receive a prompt to fetch the server-side resource pack, which includes the textures and models for the Nether ores in the generated world.
Only the server needs it, and players join without installing anything. The mod is released under the GNU General Public License v3.0 only and is open source. Files are published for Fabric only, for game version 1.21.10, with the 1.0 build dated 2026-02-03.
