Issue description

Im using the JAVA api from the wiki, and i wanted to give light to colored blocks.

However the light looks no different with or without the renderBlockLight call, i dont see anything. no colored light appears. i have a light block that changes color based on block state.

My code

    if (ModList.get().isLoaded("shimmer")) {
      LightManager.INSTANCE.registerBlockLight(LightBulbRegistry.BULB.get(), (state, pos) -> {
        if (state.hasProperty(BlockFlib.COLOUR)) {
          DyeColor colour = state.getValue(BlockFlib.COLOUR);
          System.out.println("LightManager.INSTANCE.registerBlockLight!colour" + colour.getMaterialColor().col);
          return new ColorPointLight.Template(16, colour.getMaterialColor().col);
        }
        return null;
      });

Which i targeted inside of FMLClientSetupEvent -> enqueueWork as said here https://github.com/Low-Drag-MC/Shimmer/wiki/Coloured-Lights

Steps to reproduce

i did not touch the configs at all, i simply added the mod with gradle.

Then i added only the call to LightManager.INSTANCE.registerBlockLight( for my block

are you sure that the code in LightWrapper.init be executed

[Yefancy]

btw, the color should be 0xAARRGGBB, I suppose your color is 0x00RRGGBB

[Yefancy]

int color = DyeColor.color | 0xff000000.

besides, light radius is better be set as the light value of the block (no more than 15)

[Lothrazar]

it works! thank you for that last tip. i had to mask the color just like you said , i guess the first two 'ff's add an alpha or something similar

I dont see a visual difference when i change that first value. but yeah my light Level on the block is hardcoded at 15 so this works

        DyeColor colour = state.getValue(BlockFlib.COLOUR);
        int col = colour.getMaterialColor().col | 0xff000000;
        return new ColorPointLight.Template(14, col);
