Custom Outline Banner

Custom Outline lets you change the colour, opacity and thickness of Minecraft's block selection outline. By default, it comes with the color `#ffcc00` Default Color Swatch

## Web Generator The easiest way to create a custom pack is to use the [Custom Outline Generator](https://www.nottobla.me/resource-packs/customoutline/). Select your settings, choose your Minecraft version, and download the generated pack.

## Respackopts Support Custom Outline v1.1.0 supports [Respackopts](https://modrinth.com/mod/respackopts). Install Respackopts and [LibJF](https://modrinth.com/mod/libjf), then open the Custom Outline settings through Respackopts or Mod Menu. From there, you can change the outline colour, opacity, thickness, and animation. The newest packs use Respackopts format v13 and support the newer preset system. Older packs use format v12, which supports the main settings but not the newer preset-file system. ![Respackopts Button Showing in Resource Packs](https://cdn.modrinth.com/data/cached_images/82f9efcc2e3d06dd41a42f3ee936851820c6931f.png) ## Manual Editing You can manually edit the shader if you prefer. Open: `assets/minecraft/shaders/core/rendertype_lines.vsh` Find the `#ifndef respackopts_loaded` section and change the colour values: ```glsl #define customOutline_outline_red 255 #define customOutline_outline_green 204 #define customOutline_outline_blue 0 #define customOutline_outline_opacity 100 #define customOutline_outline_thickness 1.0 ``` Save the file and press `F3 + T` in Minecraft to reload the pack. ## Rainbow Outline To use the rainbow animation, replace: ```glsl #define customOutline_outline_mode_static ``` with: ```glsl #define customOutline_outline_mode_rainbow ``` ## ⚠️ Compatibility Custom Outline is not compatible with shaderpacks that replace Minecraft's core shaders, such as Iris or OptiFine shaderpacks. If you want to use shaders with a custom outline, use a shaderpack with its own outline settings, such as: - [Complementary Reimagined](https://modrinth.com/shader/complementary-reimagined) - [Complementary Unbound](https://modrinth.com/shader/complementary-unbound) - [Photon Shader](https://modrinth.com/shader/photon-shader)

Troubleshooting

### The pack is marked incompatible Make sure you are using the version selected for your Minecraft installation. ### The settings menu is missing Install Respackopts and LibJF for your Minecraft version, then restart the game. ### The outline has not changed Make sure Custom Outline is enabled and press `F3 + T` to reload the resource pack. Also check that another resource pack is not overriding the same shader. ### The pack stops working after enabling shaders Shaderpacks may replace the shader used by Custom Outline. Disable the shaderpack or use its built-in outline settings instead.
