How to Remove the Resource Pack and Experimental World Warnings
Why These Warnings Appear
Minecraft shows a confirmation screen when you load a world that uses experimental features, and a warning when a resource pack is applied that may change gameplay. Both interrupt loading. No More Pop-Ups suppresses them by default, but you can verify or restore them in the config.
Checking the Toggles
Open the mod settings through ModMenu or Cloth Config. Look for the entries covering the resource pack warning and the experimental world warning. With both set to off, the mod skips those confirmation prompts so worlds and packs load straight through. Set either to on if you want the warning back for that category.
What Still Happens
Suppressing the warning does not change how the world or pack behaves — experimental features still function, and resource packs still apply normally. You are only skipping the informational screen. If you later want a reminder before loading an experimental world, re-enable just that toggle. Because these are client-side settings, they apply to your own game instance and do not affect other players on a server.
