Litematica Material HUD & Chest Finder

New — block verification & fixes

Ctrl + B tells you what is wrong with what you have already built. The mod compares the schematic with the real world and draws a coloured box around every block that does not match — missing, wrong block, wrong state, extra. Press it again to clear.

Why is mine better than the Litematica verifier?

	Litematica's verifier	Ctrl + B
Start	placement GUI → Verifier → Start	one keybind, no screen
Scope	the whole placement	what the panel counts — your current layers, or the Zone Focus zone
Updates	re-run the scan	live — the moment you place or break a block
Result	a list in a GUI + overlay	outlines in the world + a colour-coded chat summary

!Verification settings

!Before	!After
Before — spot the mistakes yourself	After — Ctrl + B marks every one

Both can run at the same time without conflicts.

Colour	Meaning
🟥 Red	missing block
🟧 Orange	wrong block
🟨 Yellow	wrong state
🟦 Blue	extra block

• New — markers are live: they appear and vanish as you place or break, and an area returning into render distance re-checks itself.
• New — the check follows what the panel counts — your layer selection, or the zone when Zone Focus owns the counting area. No conflicts with Zone Focus's own verification.
• New — a Verification settings tab: master switch, the four categories, see-through, box fill, draw range, box limit.

🐛 Fix — chests marked for items they do not contain

Contents are remembered per block position, and several paths wrote the wrong ones — or wrote them where no reopening could ever correct them:

• Fix — a screen that was not the chest you clicked (your inventory, crafting table, furnace, a mount's inventory, a chest minecart or boat) got recorded as that chest's contents;
• Fix — a click that opened nothing (sneak-placing against a chest, a blocked or protected chest) still armed the recording for 15 s → the window is now 3 s, and such clicks no longer arm it at all;
• Fix — two containers opened in quick succession could swap their contents;
• Fix — after a double chest was taken apart and rebuilt, the snapshot stranded on the other half stayed visible forever — every later opening wrote to a different key;
• Fix — an item-frame label kept a chest glowing for an item that had run out;
• Fix — blocks that only look like containers (crafter, chiseled bookshelf, jukebox, decorated pot, campfire, lectern) could carry a mark nothing could clear.

A mark is now shown only if opening that very container would overwrite it — anything wrong heals itself the next time you open the chest, and leftovers from older versions are cleaned up automatically.

⚠️ Known limitation — on servers where a plugin replaces a chest's screen with its own (shops, crates, protection menus), that screen is indistinguishable from a real chest for the client, so its items may still be recorded. Deleting config/layerlist_storage.json clears such records.

Changed — chat messages are colour-coded

• Changed — every line starts with a » mark in the mod's blue — messages no longer blend into each other or into server chat;
• Changed — the verification summary paints missing 🟥, wrong block 🟧, wrong state 🟨, extra 🟦 — a category at zero stays grey;
• Changed — the storage search lists block names in exactly the colours of their diamonds in the world and their stripes in the panel;
• Changed — on is green, off is grey, anything needing attention is amber.
