Biome ID Extender

by TCLProject

Biome ID Extender raises the biome ID limit of Minecraft Forge 1.7.10 so that a world can hold more than 256 biomes.

What it does

By default the 1.7.10 engine stores biome IDs in a single byte, which caps the total at 256 biomes. This Forge mod lifts that cap so mods that add many biomes can coexist in one game. The author estimates the usable range at around 50,000 IDs, and notes that keeping IDs below 65,536 is plenty for any realistic modpack.

The mod is aimed at worlds that combine large biome packs. Its notes name Biomes O' Plenty, Ridiculous World, Alternate Terrain Generation and Realistic Terrain Generation as examples that work with it, with small issues such as glass blocks generating sky under Alternate Terrain Generation and a known F3 bug where some biome names display wrong. The author calls the project a work in progress and advises against using it for worlds that matter. The client and server must both run it, since it does not change generation logic, and a world created with it will not load without it installed.

Key features

  1. Extended biome ID range

    Allows more than 256 biomes in a single 1.7.10 game, the main purpose of the mod.

  2. Known biome name bug

    Some biomes display the wrong name in the F3 debug screen, a bug the author has recorded.

  3. Dependency on the mod

    Worlds created with the mod break if it is removed, so it must stay installed for those saves.

Questions

Does Biome ID Extender work on newer Minecraft versions?

No. The only listed game version is 1.7.10, and the author notes that later versions use a different ID system, with a port mentioned only as a possible future step.

Do players need the mod to join a server running it?

Yes. Every player and the server need a copy of the mod.

Will the mod generate new biomes by itself?

No. It extends the ID limit so other biome mods can add more biomes; the author says it does not affect generation.

What the author says

This mod is still a big work-in-progress, do not use on worlds you actually care about. Worlds created with Biome ID Extender will be incompatible and break without it installed.
