JJSK Sky Fix

A small client-side compatibility addon that restores the vanilla sky and clouds in the Overworld, the Nether and the End when JJSK is installed.

The problem

If you play with JJSK (jujutsucrafts), you may notice that:

• the sun, moon and stars are gone;
• the clouds disappear;
• the sky looks like flat fog — in the Overworld, Nether and End.

This is not a shader or optimization mod issue. It happens with JJSK alone.

What this addon does
It simply registers the vanilla effects back for those three dimensions (OverworldEffects, NetherEffects, EndEffects), running after JJSK so it takes precedence.
Nothing is removed from JJSK. Its own dimensions keep their custom effects — only the three vanilla dimensions go back to how Minecraft renders them normally.
No files from JJSK are redistributed. This addon only adds its own code.
