Status

Lamium 0.2.3 is an early (0.x) release. The main settings, hotkey, HUD, target card, camera and overlay flows have been exercised in Minecraft on a local single-player setup. Map features also have external BDS checks; server coverage for other features, controllers and broad resource-pack/graphics coverage remains incomplete. Features marked experimental in the settings are still settling (see Known issues). Runtime evidence and remaining gaps are tracked in validation status.

Supported: Minecraft Bedrock 1.26.51.01, LeviLamina Client 26.51.x, Windows x64. Android support is not currently planned: it would be a separate ARM64 port, not a repackaged build. On a game version Lamium has not been checked on, the parts that depend on it (for example Night Vision's light, Edge Guard, Connected Textures, ghost blocks) stay vanilla; the settings screen, toggle toasts and a toast on joining a world say which features are paused.

Install

LeviLauncher (recommended). In an instance with LeviLamina Client 26.51.x for Minecraft 1.26.51.01, find Lamium in LeviLauncher's mod browser (Bedrinth) and install it. Update and uninstall it the same way. Updates keep your settings. Start Minecraft, enter a world and press L to open Lamium Settings.

LIP CLI (advanced). Lamium is the LIP package github.com/amatouhake/Lamium#client, the same one LeviLauncher installs (lip install github.com/amatouhake/Lamium#client in the instance folder). Only the LeviLauncher path has been tested by the maintainer.

Manual ZIP (fallback).

1. Install LeviLamina Client 26.51.x for Minecraft 1.26.51.01.
2. Download Lamium-<version>-client-windows-x64.zip from the Releases page.
3. Extract it so that Lamium.dll and manifest.json end up in <instance>/mods/Lamium/. Extracting over an older install keeps config/; do not delete the folder first. From 0.2.0 the ZIP holds no Lamium.pdb; the symbols are a separate asset (Lamium-<version>-client-windows-x64.pdb.zip), only needed to read a crash address.
4. Start Minecraft, enter a world and press L to open Lamium Settings.

Do not mix the two: a manual copy into a LeviLauncher-managed Lamium folder leaves LIP's file records out of date.

Settings are stored in mods/Lamium/config/ and the log is written to mods/Lamium/logs/lamium.log. For a manual install, deleting the whole mods/Lamium/ folder also deletes those runtime-created settings and logs. Uninstalling from LeviLauncher removes Lamium's files but keeps config/ and logs/, so a later reinstall picks the settings up again; delete mods/Lamium/ afterwards to remove them too. The managed-update ownership and preservation contract is documented in Distribution.

Features

Press L in a world or on the title screen to open Lamium Settings. Every feature has one switch there, which its key also toggles; changes are saved at once. Exp. marks an experimental feature, still settling. Key is the default key ("—": unbound until you bind one). Default is the state after a fresh install ("—": a key or screen without a switch). What each feature does in detail: Features.

Known issues

Reports, questions and translation fixes are welcome as GitHub issues; see Contributing for what helps in a report and how pull requests are handled. What has been checked in game, per feature, is in validation status.

Camera & view

• FreeCamera: underground terrain drawing is checked in a local world and on BDS; Hold/Toggle operation, menus, focus loss and dimension travel are also checked. Other players' view of the body, controllers and broader graphics/resource configurations remain untested.
• Hide effects: cannot hide the carved pumpkin overlay or the spyglass frame yet. Water, lava and powder snow fog hiding is checked with the vanilla resources in Fancy graphics; other packs and graphics modes are unverified. Under Vibrant Visuals the distance fog stays vanilla (in 0.1.8 hiding it turned the world magenta and flickering there) and Night Vision has no effect.
• Connected Textures: checked in local worlds with the vanilla resources in Fancy graphics; Vibrant Visuals, resource packs (other border widths) and servers are unverified. Only glass, glass panes, bookshelves and sandstone connect. Joined glass panes stretch their glass by one texel at the joins instead of keeping the texture's own scale (drawn that way, panes shaded dark on one half).

HUD & overlays

• Player list: knows where other players are only while they share your dimension: elsewhere it shows the dimension they were last seen in, faded, without a distance. Checked locally, on BDS and in a LAN world.
• Item icons: enchanted shields show no glint in Lamium's item icons (offhand slot, Shulker/Bundle previews, the inventory HUD); enchanted golden apples and other flat icons do. Enchanted leather armor shows its undyeable parts see-through there (unenchanted leather draws whole).

Map

• Minimap, radar and world map have local and external BDS checks with a large explored area. Waypoint storage per server, distant players on dedicated servers, and the latest section-request/teleport changes on servers remain unverified.
• Some servers may treat seeing mobs and players through walls as unfair.
• A few mob faces are not right yet (silverfish and tadpoles stay dots; camel and hoglin faces may look off), and skins with custom head models are untested.

Schematics

• Checked in local worlds only; servers, other dimensions and very large files are not verified.
• Under Vibrant Visuals ghosts lose their light-blue tint and the honey ghost is black.
• Entity models stay in their rest pose (a wolf's tail, zombie arms) with the default skin, sheep wool is not drawn, and entities without a model show as a dashed frame. Entities are checked by type near their spot and saved only by type, position and facing.
• In the 3D previews parts behind some cut-out blocks (seagrass, a spawner) can be missing, and grass and leaves take the biome you stand in.

Inventory

• All trader levels: the locked trades are checked only in local worlds.
• Inventory transfer: bulk and leave-one moves are checked in chest, furnace, brewing stand and beacon screens, locally and on a test BDS. Other screen families, other servers and rejected moves on laggy servers are untested. The held-stack Shift + click and drop gestures are checked in a chest screen in a local world only.
• Hand Restock: checked in local worlds; server timing and very fast use or ambiguous inventory changes may skip a refill. It does not refill tools (Tool Protection swaps a tool before it breaks).
• Death layout restore: checked in local worlds; with instant respawn the inventory may be read as kept and nothing is restored. Servers with latency are untested.

Actions

• Edge Guard: checked in local worlds and on a test BDS (including server position corrections); other servers and their anti-cheat are untested.
• Block Restrictions: the breaking modes will be redesigned.
• Auto Attack/Use: whether several clicks per tick land on servers is not verified.

General

• Game language: changing the game language inside a world many times in a row froze the game once (the title screen does not); Lamium allows one change per 10 seconds in a world. The cause is unknown.
• Skip server resource packs: checked on a test BDS with a cosmetic pack. Servers whose packs add blocks, items, entities or menus will show those wrong. On a server that requires its packs, the game itself turns off your global resource packs, so the look is vanilla, not your own packs.
• Simplified Chinese: the text is a first, AI-assisted translation; corrections are welcome (see Translating).

Development

The repository is the source of truth for development:

• Documentation guide indexes the docs and explains their roles.
• Design defines accepted product and UI behavior.
• Backlog defines current work, ordering and model class.
• Validation separates compiled/tested behavior from behavior actually checked in Minecraft.
• Distribution defines packaging, managed updates and settings-preservation requirements.
• Agent guide is the working manual for coding agents.
• Contributing covers issues and pull requests from outside contributors.
• Provenance separates dependencies, incorporated source and reference-only research.

Features own their transient state and restore vanilla behavior when disabled, leaving a world or losing input focus. Inventory actions use ordinary game operations and verify the resulting slot contents before continuing.

Build

Target: Windows x64, Minecraft 1.26.51.01, LeviLamina Client v26.51.5. Install Visual Studio Build Tools with the Windows SDK and C++ toolchain, LLVM (clang-cl), Git and xmake. Dependencies are resolved by xmake; no sibling project or machine-specific configuration is required.

xmake f -a x64 -m release -p windows --target_type=client -y
xmake build Lamium
xmake build LamiumTests
xmake run LamiumTests
xmake build LamiumNativeTests
xmake run LamiumNativeTests
./scripts/Check-Package.ps1

Use PowerShell 7 for the package check. xmake-requires.lock records the package versions and repository revisions used for Windows x64. Keep it when cloning; review changes from xmake require --upgrade before committing them.

The project includes a client SDK recipe that downloads the matching LeviLamina source headers and official release DLL with SHA-256 verification, then generates an import library using Visual Studio's dumpbin and lib. It does not install or bundle that runtime. See SDK build notes.

GitHub Actions builds on Windows, runs the pure and native tests plus package checks, and uploads a development artifact. Current main CI is exercised, but Minecraft runtime checks still require a local installation and cannot be proved by CI.

Use a separate launcher instance for development. Do not enable another mod that changes the same camera or inventory behavior while testing Lamium.
