\n1. Download the .zip file and extract it
\n2. Place the reduced_ores_datapack folder inside your world’s datapacks directory:
\n .minecraft\/saves\/[YourWorldName]\/datapacks\/
\n3. Create or launch your world \u2014 the datapack activates automatically<\/p>\n
Existing world
\n1. Follow steps above
\n2. Open your world and type \/reload in chat
\n3. Verify it is active with \/datapack list \u2014 you should see [file\/reduced_ores_datapack]<\/p>\n
\u26a0\ufe0f Important: Only newly generated chunks will be affected. Already explored areas keep their original ore amounts. For the best experience, use this on a fresh world or explore entirely new areas.<\/p>\n
Customization<\/p>\n
Want to tweak the reduction? Open any JSON file inside data\/minecraft\/worldgen\/placed_feature\/ and adjust the “count” value for that ore. Lower = rarer, higher = more common.<\/p>\n

FAQ<\/p>\n
Q: I installed the datapack but I still find lots of ores. Why?
\nA: The datapack only affects newly generated terrain. Already explored chunks are not changed. Venture into new, unexplored areas for the full effect.<\/p>\n
Q: Is this compatible with world generation mods like Terralith?
\nA: It depends. If the other mod also replaces vanilla ore placed features, there may be conflicts. Test on a fresh world first.<\/p>\n
Q: Can I combine this with other datapacks?
\nA: Yes, as long as they don’t also override the same ore placed features.<\/p>\n
