Many advanced addons require specific “Experimental” toggles to be active in your world settings to function correctly.
Step-by-Step Guide:
1. Open World Settings: Go to the edit menu (pencil icon) for your specific world.
2. Scroll to “Experiments”: Find the Experiments section in the sidebar.
3. Toggle Required Features: Depending on the addon, enable options like Holiday Creator Features, Custom Biomes, or Beta APIs.
4. Confirm World Copy: Minecraft will warn you that this creates a copy of your world. Accept this to apply the changes.
5. Verify Packs: Ensure both the Resource Pack and Behavior Pack are active in the “Add-Ons” tab.
