Features
This mod allows you to define skyboxes inside a resource pack that changes how the sky looks ingame. It uses the same file format as OptiFine and aims to be compatible with any skybox resourcepack made for OptiFine. A skybox defines a texture that includes 6 smaller textures that are stiched together which define what you see in the world being the top, bottom, left, right, front, and back of the world sky visually in 3d world space. You can define multiple skyboxes in a resourcepack that overlay on top of each other giving cool effects, customizability includes changing blend mode, axis rotation, speed, displaying at certain heights, and more.
