How to Fix Missing Signs by Enabling Experimental Settings
If you have loaded your world with the More Sign Variants Addon active, but the illustrated signs do not appear or fail to work properly, the world is likely missing the required Experimental Settings.
Modifying an Existing World
1. Save and quit to the main title screen if you are currently in your world.
2. Click Play to view your list of saved worlds.
3. Locate the world where you activated the addon and click the Edit (pencil) button next to it.
4. Scroll down the left-hand menu and select the Game or Experiments section.
5. Toggle the Experimental Settings switches on.
6. Confirm the warning prompt that appears when activating experimental features. (This typically creates a backup copy of your world).
7. Make sure the More Sign Variants Addon is still listed as active in both your Resource Packs and Behavior Packs tabs.
8. Load the world again and check if the illustrated signs now function.
Setting Up a New World
When creating a brand-new survival or creative world for building with these signs, scroll down to the Experimental Settings section before clicking Create. Turn the toggles on right away, then activate the addon in the pack menus so the illustrated signs load properly from the very beginning.
