Custom Block Highlight
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.


This mod provides powerful options to make the block outline look interesting for once.
Features include:
- Rainbow coloring (and gradients)
- Selective rendering of sides based on conditions (air exposed sides only, for example)
- Animations (scaling, movement, and fading)
- Support for connected blocks
- Scale adjustment
- Drawing above other terrain (yes. means you can see it through walls)
- Utilities for CPVP players
- Copying and loading configurations from files, alongside presets
- Cutting away lines at corners or centers
- Entity hitbox, fluid source block support, and block model support
- Line layers
