Ringo's Terraria Core

by ringoway

Ringo's Terraria Core adds Terraria-style biomes and some related content to Forge worlds for 1.20.1.

ForgeClient and serverAll rights reserved1.20.1

What it does

The mod adds two biomes modeled on Terraria, the Corruption and the Crimson. Each spreads its surface blocks into nearby terrain. Spreading and generation can each be disabled in the config. TerraBlender is required. The mod is published for Forge and runs on the client and the server, so both sides need it. Files are published as beta builds under All rights reserved, and the mod is not open source.

Key features

  1. Corruption biome

    A Terraria-style biome whose blocks spread into nearby terrain, with its own plants and sub-items.

  2. Crimson biome

    A second biome that spreads its blocks into surrounding ground, with plants and sub-items of its own.

  3. Config options

    Spreading and generation of the two biomes can each be turned off in the config file.
