Getting Started with The One Probe

Probe helmets and the overlay

The One Probe adds helmet-mounted probes that show information about whatever block or entity you are looking at. Instead of a separate tool, the probe is attached to a helmet, so the readout appears as an overlay while you play.

Several helmet variants exist, each pairing the probe with a different helmet material. There is also a dedicated probe item and a bauble version, plus a creative-only probe. The exact helmet you craft determines the material, but the core behavior is the same: wear it, look at something, and the overlay reports on it.

The overlay is configurable, so you can adjust how and when information is displayed. A built-in readme item is included in-game, which is the best place to check the details for your setup rather than guessing at values.
