Just Like Rays Mod reworks standard block lighting so light spreads more like real light in your world. Torches and glow blocks cast circular light shapes instead of square blocks, while solid walls block the rays to create dark shadows behind them. This mod runs on the server side and changes how save files store light, meaning you do not need shaders to see realistic shadow shapes around your base.
