Expected Behavior

Blocks that emit light (e.g.: redstone lamps, furnaces) should look bright when turned on, even if they have a 3D model.

Actual Behavior

While they still emit light, the inner part of full blocks (that can emit light) that have a 3D model look very dark (as if they were somewhere with light level 0).

Reproduction Steps

1. Get a resource pack that adds 3D models to blocks that emit light (personally I use Lithos 3D, which also requires Lithos Core)
2. Go in a world and place a block that can emit light and has a 3D model (in Lithos 3D you can use furnaces)
3. Place the block and turn it on (if necessary), it should look normal/bright
4. Restart your game with Sodium and look at it again, it should look really dark even when turned on
