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!

Current Features

SeedMapper Core

• Integrates SeedMapper into the client (no external mod workflow required).
• Supports locating structures, biomes, slime chunks, ore veins, terrain, caves, canyons, and loot.
• Supports mineshaft, desert well, amethyst geode, canyon, nether fossil, and 26.3 abandoned camp locating.
• Includes infested ore (silverfish blocks) in ore highlighting.
• Renders SeedMapper results on the world map and minimap.
• Tracks completion state for located targets.
• Provides saved seeds, manual seed input, and per-world/per-server SeedMapper state.
• Stores custom structure salts per world and server for datapack and modded structures.
• Provides a buried-treasure cluster finder that scans the world border for rare multi-treasure formations.
• Provides Trial Chambers vault loot prediction with normal and ominous reward tables.
• Bundles cubiomes support through SeedMapper's Fork.

Entity Display & Markers

• Detects loaded-chunk 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.
• Marks End-ship markers with a red slash when their item frame no longer contains an elytra, including after a player removes it.
• Supports optional marker clustering: matching nearby markers collapse to one Minecraft icon with a white count and separate again while zooming in.
• Persists detected markers per server and dimension, restores them after reconnecting, and updates them when their chunk is rescanned.
• Updates loaded entities through live block/chunk hooks without waiting for a full render-distance sweep.

Map Icon Scaling

• Provides separate Map Entities Scale and Minimap Entities Scale controls for portals, end portals, end gateways, containers, workstations, redstone, and spawners.
• Minimap entity scale defaults to 0.6x and is capped at 1.2x; fullscreen map entity scale remains independent.
• Provides separate SeedMapper structure-icon scale controls for the minimap and fullscreen world map under SeedMapper's World and Structures settings.

SeedMap

• Predicts biomes and terrain from the configured seed, independently of explored terrain data.
• Uses world-aligned sampling across zoom levels, with individual-block biome sampling at close zooms and multiple samples for coarse texels.
• Gives the visible map priority over off-screen padding when allocating preview resolution, so dragging does not lower the requested detail level.
• Shows the biome preview first, then refines terrain shading on a bounded, interpolated height grid. SeedMap terrain shading is a prediction rather than a full block-by-block world render.
• Provides Preview Resolution up to 4096 under World Map → Seed Map, alongside preview cache, padding, terrain-style, and update-while-moving controls. Existing saved resolution values are preserved.
• Keeps cursor biome lookups asynchronous and cancels obsolete preview jobs when the map closes or its context changes.

SeedMapper Menu

Locate Structures

SeedMapper Commands

• Exposes local command roots: /seedmap, /sm, /voxelmap, /vmap.
• Supports locate, highlight, vault, treasure-cluster, and source-chain commands.
• Provides a standalone SeedMap screen and a buried-treasure cluster search.

ChunkAnalysis

• Generates vanilla ProtoChunks in memory from the configured seed and current vanilla dimension, through structures and features, without saving chunk data.
• Best results if client version matches server version.
• Conservatively compares seed-derived block types with loaded multiplayer chunks: red is expected-but-missing, blue is unexpected, and yellow is a changed block type.
• Ignores exact state properties, fluids, and randomly ticking blocks because normal simulation can change them without player input.
• High-confidence filtering also removes vegetation/decorative noise, unexpected natural terrain, and ambiguous swaps between natural terrain materials.
• Detects player-shaped voids with a fast connected-component morphology pass and promotes likely tunnels, shafts, stairs, rooms, and excavations to deep red.
• Provides /seedmap chunkanalysis voids [radius], which skips biome decoration and features for a faster void-only scan.
• Tracks decoration-stage writes separately from stable terrain, so arbitrary replacements in seed-derived terrain are detected without a block whitelist; chunks with strongly bidirectional cave disagreement are reported and filtered as incompatible baselines.
• Uses transparent tinted block-model ghosts or optional solid ESP fills, with fair sampling across scanned chunks and configurable performance limits.
• Supports scan, voids, audit, unexpected, continuous, clear, status, and ghost modes from both commands and the ChunkAnalysis settings screen.
• Provides vanilla-worldgen Ore ESP through /seedmap chunkanalysis esp ore <block> [chunks] (or /seedmap chunkanalysis ore <block> [chunks]).
• Generates Ore ESP positions from ChunkAnalysis's in-memory vanilla ProtoChunks rather than SeedMapper's Cubiomes ore-placement path.
• Provides Ore ESP target and chunk-radius controls with autocomplete for diamond, iron, gold, emerald, copper, coal, lapis, redstone, Nether ores, ancient debris, and infested blocks.
• Provides a dedicated Ore ESP color in the ChunkAnalysis color options.
• Able to find tunnels, holes, stairs faster than traditional "TunnelHoleStairESP" hacks in modded clients.

ChunkAnalysis ESP

• SeedMapper predicts ore placement with Cubiomes. Chunk Analysis regenerates the chunk using Minecraft’s own world-generation code, then scans the generated result for the selected ore.
• Differences can depend on MC/Client version mismatches or anti-xray implementation. One may benefit you over the other.
• Blue is ChunkAnalysis ESP and Red is SeedMapper's ESP.

SeedMapper ESP, Tracing, and Loot Workflow

• Renders ESP for blocks, ore veins, caves, canyons, and terrain.
• Provides surface ESP, which highlights only the topmost predicted block of each column.
• Supports terrain ESP in the Nether and End as well as the Overworld.
• Provides configurable ESP style profiles for fill, outline, color, alpha, and timeout behavior.
• Provides a highlight/tracer workflow for located structures and loot results.
• Hides highlights automatically when the player is near a target.
• Provides an integrated loot viewer with search by name, ID, enchantments, and NBT-like terms.
• Opens loot views for Trial Chambers, Ancient Cities, and Trail Ruins.
• Provides vault loot prediction directly from Trial Chambers markers on the world map.
• Retains loot tables so container loot remains identifiable after it has been generated.
• Keeps ESP and ChunkAnalysis overlays visible above terrain when viewed from above.
• Able to ignore checking against the world which may help against anti-xray.

Datapack Structure Support

• Imports datapack structures for SeedMapper.
• Applies custom structure salts to world-map markers, locator queries, and loot lookups.
• Provides datapack URL, cache path, autoload, and enable controls.
• Provides icon style and color scheme controls.
• Persists datapack structure enable/disable state per world.
• Persists markers located from datapacks.
• Clears SeedMapper loading text reliably when the map is hidden or disabled and after exact results resolve.

Baritone Integration

• Integrates with Baritone through BaritoneHelper.
• Provides an automatic ore vein miner that detects exposed ore veins and uses Baritone to strip-mine them.
• Requires Baritone to be installed separately.

CPU Renderer

• Provides a full CPU-based radar renderer as an alternative to the GPU pipeline.
• Makes CPU rendering available through the Enable CPU Rendering setting.
• Supports block-helmet rendering on the CPU path.
• Provides VoxelMap compatibility with Vulkan and other renderer-modifying mods.

Rendering and Compatibility

• Routes minimap and world-map rendering through Iris-compatible helpers so minimap text, icons, and mob icons remain visible with Iris shaderpacks.
• Uses Geckolib-backed entity rendering for compatible mob icons, including armor and entity variants.
• Handles retina display scaling for world-map rendering and coordinates.
• Rebuilds resource-backed map, icon, and entity data correctly after resource reloads.
• Keeps rendering pipelines and overlay depth ordering compatible with the ChunkAnalysis, ESP, entity, and world-map layers.

World Map Improvements

• Renders SeedMapper marker icons and loot markers on the fullscreen map.
• Renders buried-treasure cluster markers with treasure counts on the fullscreen map.
• Provides a standalone SeedMap screen with drag-to-pan, scroll-to-zoom, and coordinate inputs.
• Provides a Biome Sample Y control so seed-map biomes are sampled at the selected height.
• Supports deeper SeedMap zoom in and out, with Shift for faster steps.
• Supports touchpad/trackpad pinch zoom on the SeedMap and fullscreen map.
• Provides marker context actions for completion toggles, loot actions, and waypoint interactions.
• Provides configurable transport shortcuts for teleport, flight, pathing, and other client/server commands.
• Provides transport shortcut controls for excluding Y coordinates and showing all shortcuts in the main menu.
• Transport shortcut names, commands, visibility, and client-command flags persist across launches.
• Persists world-map plot lines with editing, duplication, deletion, color, thickness, and cross-dimension support.
• Supports visible-area export.
• Provides coordinate recentering/editing and a player recenter action.
• Handles deep zoom-out and performance mode with improved texture processing and rendering.
• Keeps waypoints visible in world-map performance mode when selected.
• Displays the zoom ratio and blocks per pixel in the fullscreen map header.
• Provides improved waypoint layering, depth handling, label ordering, icon rendering, and highlighted-waypoint alpha.
• Handles world-map cache locations and chunk readiness checks safely.
• Protects cache writes and decompression; stale cache data may require clearing after an upgrade.
• Handles world-map input for right-click actions, coordinate editing, autocomplete, and resizing without losing screen values.
• Supports player and dimension-aware world-map state, including custom-server dimensions and aliases.

Detail, Visibility, and Performance

Fullscreen map detail, visibility, rendering, and zoom controls are in the sidebar options screen under World Map.

• Detail provides Full Detail and Balanced presets, independent chunk-trail and new/old-chunk resolutions, explored-terrain resolution, and automatic layer hiding controls. Full Detail keeps all layers visible, uses exact chunk overlays, and selects all explored-terrain pixels.
• Visibility by Zoom provides separate sliders for terrain, chunk trails, trail nodes, new/old chunks, waypoints, waypoint names, entities, and SeedMap biomes. Each slider ends with Always.
• Rendering offers Automatic, Cached image, and Geometry overlay modes, image scaling, smoothing, and optional marker reduction while moving or at high counts.
• Zoom & Storage controls the zoom limits, scroll steps per doubling, zoom snapping, and Retained Zoom View Cache. Completed views are reused for repeat zooming within a configurable memory budget; older views can be evicted.
• Display → Show Loading Bars enables or disables the individual loading bars at the bottom left.
• Culls off-screen overlays, caches sparse chunk queries and completed map views, and schedules preview work separately from explored-terrain loading. Geometry is split into batches to stay within the renderer's vertex limit.

Full Detail applies to explored terrain and overlays. SeedMap's preview resolution and terrain shading have their own sampling limits; higher preview resolution requires more computation and memory.

Chunk Options

ChunkSync/Sharing

ChunkSync lets you securely share chunk-layer data with other players.

One-Time Setup

• /chunksync key <passphrase>
• /chunksync host <litterbox|file.io>

Share

• /chunksync share

• /chunksync share to <name>

  • Exports your chunk-share bundle.
  • Encrypts it with your configured passphrase.
  • Uploads it to the selected host.
  • Posts (or whispers) an encoded import token.

Receive

• /chunksync get <code>

• /chunksync get <code> as <name>

  • Default get merges into your own layer.
  • as <name> imports as a separate colored player layer.
  • Chat prompt import actions use the separate-layer flow automatically.

Manual File Transfer

• /chunksync export [name] writes voxelmap/chunk_share/<name>/ (folder or zip workflow supported).
• /chunksync import [name] [as <name>] imports a local folder or .zip bundle.

Manage Imported Layers

• /chunksync players
• /chunksync remove <name>

UI and Settings

• Provides a dedicated SeedMapper options tab and related screens.

• Provides Advanced → Servers & Seeds → Manage Server Seeds, with search and All servers / With seeds / Without seeds filters.
• Lists saved Minecraft servers, VoxelMap server/world seed records, and SeedMapper overrides, with controls to copy, edit, or delete a seed. Seed edits preserve waypoint records; deleting a seed does not delete the server's map data.
• Provides Chunk management UI.
• Provides ChunkSync management UI for passphrase, sharing, receiving, manual import/export, player layers, and status.
• Uses the VoxelMap x SeedMapper by CevAPI branding.
• Includes localization keys for SeedMapper, ChunkSync, and the current 26.3 settings.

• Provides the rendering pipeline, overlay types, and mixin integrations required by the current overlays.
• Migrates world-map data and settings safely when legacy layouts are encountered, including recovery after cancelled world-preview migration.

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 off to stop update notifications.

Loader and Build Support

• Registers SeedMapper and ChunkSync client commands for the supported loaders.
• Extracts the cubiomes native library into the game directory and falls back to the launcher natives directory when needed.
• Reports cubiomes loading failures in SeedMapper instead of showing a blank seed map.
• Targets Minecraft 26.3 with Fabric API 0.161.0+26.3 and NeoForge 26.3.0.16-beta.
• Uses VoxelConfig as a shared library and prebuilds it in GitHub Actions for CI builds.
• Uses the current project metadata and fork versioning.
• Names build artifacts voxelmap-x-seedmapper_<minecraft-version>_<loader>_v<version>.jar.
• Integrates with Fabric Mod Menu for the configuration screen.
• Provides Cubiomes Minecraft-version selection with an automatic client-version mode.

Notes

• This fork is feature-focused and not intended as strict upstream parity.
• Some legacy localization keys may still exist after UI refactors.
• On Linux, the bundled libcubiomes.so requires glibc 2.34 or newer (Ubuntu 22.04+, Debian 12+).
• Existing world-map cache files can contain stale or damaged region data; remove .minecraft/voxelmap/cache once when upgrading if visual artifacts persist.
• The project remains under active development, and occasional regressions are possible.
