Configuration

The preview outline

While holding an infused pickaxe in 1x3 or 3x3 mode, a subtle outline traces which blocks are about to break, at reduced brightness so it stays readable without dominating the world. 1x1 never draws anything extra — that's vanilla's own block-targeting box, untouched.

The preview is purely client-side and cosmetic; turning it off never changes what actually breaks.

Turning it off

With Mod Menu installed: open Mod Menu and select Amethyst Excavation. The screen has a single option, Show area preview, which you can toggle directly.

Without Mod Menu: edit the client config file by hand. Mod Menu is never required — the mod starts and works normally without it.

The config file

Location: <your instance>/config/amethyst-excavation.json

{
  "showExcavationPreview": true
}

Set showExcavationPreview to false to disable the outline. The preference is read on startup and persists across restarts. If the file is missing or unreadable, the mod falls back to its default (true) rather than failing to launch.
