When You Need Atmospheric Radiance Overhaul (And What Happens Without It)

If you found Atmospheric Radiance Overhaul in a modpack or installed it as a requirement, you might notice that it does not add any blocks, items, or settings menus to your inventory. Its entire purpose is to work quietly in the background to prevent two major visual mods from clashing.

What the Mod Actually Does in Game

Normally, custom weather mods change how the sky, clouds, and storms are drawn, while Iris Shaders also completely replaces the game's lighting and sky rendering pipeline. When both try to control the sky at the same time, they conflict. Atmospheric Radiance Overhaul connects the two mods so that custom stormy weather renders properly while shader packs are active.

What Happens If You Remove It

Whether you need to keep this mod depends entirely on how you play:

• If you use both Iris Shaders and the custom weather mod: You must keep this mod installed. If you remove it, turning on a shader pack will cause graphical glitches, rendering conflicts, or broken storm visuals whenever custom weather occurs.
• If you play without shaders: If you never enable shader packs in your Video Settings, the rendering conflict will not trigger, though leaving the mod installed will not harm your game.
• If you are setting up a dedicated server: You can safely leave this mod out of the server files, because it runs strictly on the client side.
