by RustySnail

What it does

Before a world is created, the Create World screen gains a tab that renders a preview of the generated terrain for the chosen seed. The preview draws on TerraFirmaCraft's own world generation, so the maps reflect the terrain the game will produce. Heightmaps are enabled by default in the preview.

The tab can show several overlay maps at once: rainfall, temperature, land, water and river areas, rock layers, and biome data including kaolin clay. Players can use these to check whether a seed has the climate, rock types or water layout they want before committing to a world. The mod is a fork of World Preview NeoForged that adds TerraFirmaCraft support.

The mod requires TerraFirmaCraft, and it needs NeoForge for Minecraft 1.21.1. ArborFirmaCraft is an optional dependency that adds its own content to the previews. Files are released under the Apache License 2.0 and the source code is open source. The screen runs on the client, so servers do not need the mod.

Key features

  1. World Preview tab

    A tab on the Create World screen shows a terrain preview for the entered seed before the world is generated.

  2. Climate maps

    Rainfall and temperature maps show how the climate is spread across the previewed area.

  3. Land, water and river maps

    Separate maps mark land, water and river areas so the shape of the terrain is readable at a glance.

  4. Rock layer maps

    Rock layer maps display the rock types and layers that TerraFirmaCraft generates in the previewed area.
