Colors & Tints - jedlimlx/supplemental-patches GitHub Wiki

In order to add new colors and tints for Advanced Colored Lighting (ACL), .json files can be added under folders named colors and tints.

The code will be injected into /shaders/lib/colors/blocklightColors.glsl.

There is only one field that needs to be filled in, which is the code field. It contains a single line of GLSL code that outputs a vec4 (or a vec3 for tints).

The first 3 components are the RGB components of the color and the last component is the amount of additional light that the block should emit (in addition to normal Minecraft blocklight).

Additional code can be injected into /shaders/lib/colors/blocklightColors.glsl by placing .glsl files within the colors/injects folder. This can be used to define additional processing before the code within the .json.

For example, if you want to have an option to change the color of light emitted, you can do something like the following.

#ifdef CHANGE_COLOR_OPTION
    vec3 yourColor = <your color>
#else
    vec3 yourColor = <some other color>
#endif

{
    "code": "vec4(yourColor, 0.0)"
}
