The mod currently only adds white lights to the. game i.e. when you play with shaders, only white light is emitted by all the blocks no matter the color.

It will be fixed in the next update asap. But, for the time being, you can do the following:

1. Go to \minecraft\Instances (your modpack here) \shaderpacks\ComplementaryUnbound_r5.2.2.zip\shade rs\block.properties

2. Open block.properties (You may need to unzip the shaderpack, its okay, you can rezip it later)

3. Download the block.properties or copy the contents form Pastbin.com that includes the Modern Lights blocks and either replace the original block.properties file with the new one, or open the new one, select everything, and paste it in the old one.

4. Rezip the shaderpack if needed, and reload your world. and you're done

Before

After

Thanks to twilightknight2545 (Melody!) over on discord for pointing the issue out and providing the updated block.properties file the before and after images, I really appreciate it.

• All the blocks can now also be toggled on/off by redstone :D [right clicking still works unless the block is being powered by redstone]

• Added Vertical Slabs!

• All the blocks can now be placed on walls and fences.

• Now when you make a map, each[except the non solid blocks like Mini Lights, Mini Blocks, etc]  will show their respective color.

• All the blocks are now waterloggable

• Changed the crafting recipe of Luminous Block [see Gallery]
