In-game Minecraft mod that allows you to compare natural terrain to your current terrain. For questions please go to my Discord.

This mod does not yet support terrain generation of Minecraft version 1.12.2 and below. Support for these versions will be added later.

Before using any of these commands, make sure the seed has been configured using /seedmapper:config seed set <seed>.

Usage: /seedmapper:seedoverlay [<version>]

Shows an overlay of blocks that don't match the seed's default terrain. Based on the biome, certain blocks are "ungenerated". For example, sand will match in a desert, but not in a forest. The combination of terrain comparison and ungeneration makes for a great overlay.

Usage: /seedmapper:terrainversion

Determines the Minecraft version the terrain has most likely been generated in. This command internally used the SeedOverlay principle.

Usage: /seedmapper:locate (biome <biome> <version>)|(feature (structure <structure> <version>)|(slimechunk <version>))|(loot <item> <version>)

Locates a given feature, biome or loot item closest to the player. Depending on the rarity of the biome or loot item, this process can take at most 30 seconds.
