Credits goes to Tixul for the original Story Mode Cloud's pack.
Story Mode clouds but for earlier versions, since they're the most modded.
I'm aware of the existence of Cloud Tweaks but it's a bit resource heavy on earlier versions.

Like the original, it doesn't work with shaders.
If you want it to work with sodium or embeddium; navigate to the config folder to find the file & put this in in either "embeddium-mixins.properties" or "sodium-mixins.properties" depending on what you use:
mixin.features.render.world.clouds=false
It'll say it's "incompatible with sodium" but it'll still work.
