A tiny fabric mod that disables shading on the sides of blocks which makes lighting look flat. This is similar to the Old Lighting setting set to OFF with Optifine's internal shaders.
This mod has no dependencies, it doesn't even need Fabric API. It is compatible with Sodium as of version 1.2.0.
The mod is quite small and should work on most versions, you can check the versions listed on each upload to check its compatible versions.
