It will change many aspects of your game, some which includes shadows, torch light, sunlight, moonlight and other. Changelog Updated the base code from 1.16.0 to 1.16.221. Implemented shaders for shader-generated sun and moon (#52). The moon shader does a diffuse lighting to render lunar phases. Added a configuration item "ENABLE_SHADER_SUN_MOON" which is enabled by default. Disabling it will revert the sun and the moon to the default texture-based rendering. The waving animation of plants used to happen even indoors. It is now fixed (#85). The waving animation of plants used to have a discontinuity at each of chunk borders. It is now fixed too (#85). The perturbance of water also significantly decreases indoors now.
