VoxelMap x SeedMapper by CevAPI

VoxelMap x SeedMapper is a heavily modified fork of VoxelMap Updated that integrates SeedMapper directly into the client and extends VoxelMap with advanced chunk overlays, data sharing, and world-map tooling. Perfect for base and structure loot hunting!
What This Fork Adds
SeedMapper Core
- Integrated SeedMapper into the client (no external mod workflow required).
- Added locating for structures, biomes, slime chunks, ore veins, terrain, caves, canyons, and loot.
- Added world-map and minimap marker rendering for SeedMapper results.
- Added completion tracking for located targets.
- Added saved seeds, manual seed input, and per-world/per-server SeedMapper state.
- Added bundled cubiomes support (SeedMapper's Fork).
Entity Display & Markers
- Added live loaded-chunk detection for containers, workstations, redstone components, spawners, and trial spawners on both the minimap and fullscreen world map.
- Container filters include single chests, double chests, trapped chests, ender chests, shulker boxes, barrels, hoppers, dispensers, droppers, brewing stands, and crafters.
- Each category can be enabled independently, with a
...submenu for choosing individual block types. - Added Elytra Detection: End-ship markers receive a red slash when the item frame no longer contains an elytra, including after a player removes it.
- Added optional marker clustering: matching nearby markers collapse to one Minecraft icon with a white count, then separate again while zooming in.
- Added optional Marker Persistence. Detected markers are stored per server and dimension, restored after reconnecting, and updated when their chunk is rescanned.
- Added live block/chunk update hooks so loaded entities update without waiting for a full render-distance sweep.

Map Icon Scaling
- Added separate
Map Entities ScaleandMinimap Entities Scalecontrols for portals, end portals, end gateways, containers, workstations, redstone, and spawners. - Minimap entity scale defaults to
0.6xand is capped at1.2x; fullscreen map entity scale remains independent. - Added separate SeedMapper structure-icon scale controls for the minimap and fullscreen world map under SeedMapper's World and Structures settings.

Update Checking
This fork includes an in-client update checker/notification system.
Common commands:
/voxelmap updatechecker status/voxelmap updatechecker off/voxelmap updatechecker on/voxelmap updatechecker toggle/voxelmap updatechecker check
Quick disable:
- Run
/voxelmap updatechecker offto stop update notifications.
Notes
- This fork is feature-focused and not intended as strict upstream parity.
- Some legacy localization keys may still exist after UI refactors.
- Existing world-map cache files can contain stale or damaged region data; remove
.minecraft/voxelmap/cacheonce when upgrading if visual artifacts persist. - Active development is ongoing; occasional regressions are still possible.

0.9Релиз26.2 · 2 июля 2026 г.
Added
SeedMap — New worldmap preview powered by seed data. Features include: a flat default style selector, parallel + cached generation with bulk texture upload, correct layering under explored chunks, configurable padding/quality/cache settings, and a biome-under-cursor readout. Height/topo ocean colour palette and level have also been tuned.
Baritone Integration — Custom Baritone integration via
BaritoneHelper, including an automatic vein miner for ores. Works alongside the Baritone mod to automate strip-mining of exposed ore veins.Sulfur Caves Support — Added a Sulfur Caves map filter, a sulfur cube icon, and updated cubiomes native libraries + jextract bindings to SeedMapper 2.27.0 (MC 26.2 worldgen).
CPU Renderer (Vulkan Compat) — A full CPU-based radar renderer as an alternative to the GPU pipeline, configurable via a new option. Includes block helmet rendering support for the CPU path, making VoxelMap compatible with Vulkan.
