VoxelMap x SeedMapper (VoxelMapper)
by cev-api
VoxelMapper is a client-side Fabric map tool that integrates SeedMapper into VoxelMap, so structure and biome locations appear on the world map.
What it does
Players use the integration to locate structures such as mineshafts, desert wells, amethyst geodes, canyons, nether fossils and abandoned camps, along with biomes, slime chunks, ore veins, caves and loot. Results are drawn onto the world map and the minimap, and found targets are tracked until marked complete. Saved seeds, manual seed entry and per-world or per-server SeedMapper state keep each game separate, and custom structure salts can be stored for datapack or modded structures.
Its client requires SeedMapper as an external mod, and the fork also includes infested ore and silverfish block highlighting. Full Detail applies explored terrain overlays, while SeedMap's preview resolution, terrain shading and sampling limits can be adjusted, with the note that higher preview resolution needs more computation and memory.
The mod is published for Fabric only, across five release versions 26.1 – 26.3, under All rights reserved, and it is not open source. Its source code and issue tracker are public. Build 0.14 for 26.3 is the latest file, dated 2026-10-09.
