THIS ONLY WORKS WITH SHADERS!
It will not modify the vanilla sky.
The Twilight Forest with sky settings changed to end, with the shader Solas.
Behavior
This mod lets you change how you view the sky for every dimension, allowing you to set the dimension's sky to Overworld, Nether or End, in case you prefer one of these.
Configuration
Modifying the settings is really easy. In game, click the Mods button on the pause menu, find Shader Sky Configuration and click Config.
This will open a screen that lets you modify the sky by cycling through buttons for each dimension entry, with a Reset button next to it and a scroll bar (or you can just scroll) in case there's more entries than shown on screen. 
Compatibility
Compatible with Iris 1.8.14-beta.1+mc1.21.1.
The mod is completely client side.
