Simple Block Overlay Mod (1.21.7, 1.20.1) is a lightweight yet powerful client-side enhancement that gives you complete control over the visual block overlay that appears when targeting blocks in Minecraft. In the vanilla game, the block you aim at is highlighted with a subtle, dark translucent outline. While functional, this default appearance may not suit every player’s preferences or visibility needs especially in high-resolution monitors or custom shaders.
This mod allows you to take full control over how block outlines appear in your game. You can change the color, opacity, thickness, and even the rendering style of the block overlay. Whether you’re looking for a cleaner aesthetic, a vibrant glow, or simply a more visible highlight for better accessibility, Simple Block Overlay offers the customization tools to do it.
Perfect for builders, PvP players, and modpack developers who want more visual clarity or stylistic consistency, this mod improves the user experience without altering any core gameplay mechanics.
