Selective Bounds Mod (1.21.1, 1.20.1) – Smart Block Outline Control

Available for:FabricForgeNeoForge

Selective Bounds Mod tackles one of those small Minecraft annoyances that most players never realize bothers them — the ever-present block selection outline. Instead of showing that wireframe box on every single block you glance at, this mod intelligently hides it when it serves no purpose, like when you're holding the wrong tool or simply walking past foliage. The result is a noticeably cleaner, less cluttered view that lets you appreciate your builds and the world around you without constant visual noise.

Key Features

  • Context-Aware Outline Visibility — The block selection outline automatically hides when you're holding the wrong tool or have no tool equipped. This is especially effective around foliage and non-solid blocks where the outline typically adds clutter without providing useful information.
  • Temporary Override — The outline reappears the moment you start breaking or placing blocks, so it never gets in the way of actual gameplay. You can also hold Shift at any time to force the outline back on when you need precise block targeting.
  • Fully Configurable — Every behavior can be fine-tuned through a configuration file located at configs/selectivebounds.json, giving you full control over when outlines appear and disappear.
