CauldronHUD

CauldronHUD is a clean look-at info layer. Point your crosshair at any cauldron and a small readout appears in the top-left of your screen telling you exactly what it holds and how full it is:

• Empty — a plain cauldron, nothing inside
• Water 1–3 / 3 — a water cauldron and its current fill level
• Powder Snow 1–3 / 3 — a powder snow cauldron and its level
• Lava (full) — a lava cauldron

Why

Vanilla only hints at a cauldron's contents through a small texture change inside the block, and the exact fill level is hard to read at a glance — especially from a distance or across a row of cauldrons. CauldronHUD puts the precise content and level on screen so you always know whether a dyeing/leather-washing station, a powder snow trap, or a water/lava store is ready to use, without dipping a bucket or walking right up to it.

Details

• Pure client-side info HUD — reads the cauldron's vanilla block state only. No mixins, no block entities, no gameplay changes.
• Toggle the HUD on/off with U.
