This shader is at its EOL, and will not be updated or supported.
Iris and Optifine, as well Sodium and Minecraft as they update have made a multitude of changes to rendering since the last version this shader was written in (Minecraft 1.18.2), and as such things are bound to break.
With all default settings, the shader does work up to Minecraft 1.21.1, Iris 1.8.5, and Sodium 0.6.8. However turning off waving liquids will cause the shader to not work in non-overworld dimensions from at least Minecraft 1.19.4, Iris 1.5.2, and Sodium 0.4.10, with a high likelihood of earlier versions.
This simple, vanilla-like shader adds:
- Shadows & Softer bluer lighting
- Water that waves, lava does the same too!
- Shadow strength depending on the time
- Nether & End support for shadows
