About this project
What does Flat Lighting add?
Flat Lighting 💡
Adds a new video setting to make lighting flatter. It does this by removing the shading differences between the sides and top of blocks, which gives the game's lighting a softer or flat appearance.
The effect is similar to the Old Lighting setting from Optifine's internal shaders.
