This is a client-side mod that hides the block outline when aiming at specific blocks.
Originally designed for barrier blocks, it now supports any block you want by using a configurable list.

The mod allows you to fully control when and where the outline should disappear:

• Enable or disable the feature at any time
• Choose which game modes should hide the outline
• Add or remove any blocks from the hide list
• All config changes apply immediately in-game without restarting

Because the mod affects only rendering, it does not need to be installed on the server and does not affect gameplay or world data.

Perfect for map creators, adventure maps, lobby design, cinematic use, or any situation where block outlines break immersion.

Config Guide

The config file is located at: config/no_barrier_outline-client.toml

1. Enable or disable the mod

enabled = true

Set to false to completely turn off the mod.

2. Choose game modes where the outline is hidden

game_modes = ["survival", "adventure"]

Supported values:

• survival
• creative
• adventure
• spectator

If the player is not in one of these modes, the outline will render normally.

3. Select which blocks should hide their outline

hidden_blocks = [
    "minecraft:barrier",
    "minecraft:glass",
    "minecraft:stone"
]

Use full block IDs from the Minecraft registry:

• "minecraft:barrier"
• "minecraft:glass"
• "minecraft:oak_planks"
• "minecraft:bedrock"

You can add as many as you want.

How it works

When the player looks at a block, the mod checks:

1. If the mod is enabled
2. If the current game mode is allowed
3. If the block is in the hidden block list

If all conditions match, the default white outline is canceled.
Changes to the config become active almost instantly during gameplay.
