Xaero Seedmap

by TGdoesCode

Xaero Seedmap fills the unexplored parts of Xaero's World Map with terrain predicted from the world seed, so the map is not left as black empty regions.

What it does

Before a player has walked through an area, the map shows biomes, terrain shapes and naturally generated structures calculated from the world seed. The result is a map that looks populated from the start, which helps a player plan a route or spot a point of interest without first exploring each chunk.

Terrain generation also places select structures such as villages and temples on the map, giving the player a sense of where notable features lie. The mod is client-side only and needs Xaero's World Map to be installed as well. Fabric is the only loader with files, and the latest build, 26.4.3, targets 1.21.8 and was published on 2026-04-03 under the MIT License, with the source code available.

Key features

  1. Predicted terrain

    Unexplored chunks are drawn with biomes and terrain shapes predicted from the world seed.

  2. Seed-based structures

    Villages, temples and other structures determined by the seed appear on the map before they are visited.

  3. Fewer blank regions

    Areas that have not been traveled show generated terrain instead of the default black of the world map.

  4. Planning aid

    Players can pick routes and locate interesting areas from the map alone, without scouting each chunk.

What the author says

This mod enhances Xaero’s World Map by intelligently filling in unexplored areas using the world’s seed. Instead of the default black or empty regions where the player hasn’t traveled yet, the map is dynamically generated to display terrain as if it had already been explored. By leveraging the world seed, the mod can…
