Polymerized Nether Ores
Polymerized Nether Ores is a server-side mod that generates nether versions of all your ores (vanilla/modded). It uses (and depends on) Polymer to generate the textures for the client.
Server-side functionality
This mod is server-side only. All logic is handled by the server, meaning players do not need to install the mod locally to see the custom blocks.
Upon joining, players are prompted to download a server-side resource pack. This pack includes the textures and models for all Nether ores generated in the world.
Features
- Compatibility: Automatically generates Nether variants for both vanilla and modded ores.
- Standard Mechanics: All block interactions remain unchanged. Enchantments (such as Fortune and Silk Touch), furnace smelting, and mod-specific processing work exactly like the original ores.
- No Client Modding: Players can join using a standard vanilla client and still see all custom ores.
Automatic Resource Pack Hosting
To automate the resource pack delivery without manually handling .zip files, you can use Polymer's built-in Auto-Host feature:
- Install the mod and Polymer, then start the server once to generate the configs.
- Navigate to
/config/polymer/auto-host.json. - Set both
enabledandrequiredtotrue:
"enabled": true,
"required": true,
This will automatically generate and host the resource pack for any player who joins.
