Ore Cluster Worldspawn

Ore Clusters

To get Ore clusters spawn in your world you need to use COFH core world spawning. Place a new file into '/config/cofh/world' folder and name it anyway you want (end with .json) and paste the following code, you can disable clusters of ores you don't have or change the rarity. If you have a cluster enabled but don't have the ore, they will have black color and provide cobblestone, no crash will happen.

Since 1.2_Alphatest3 version you can define custom ore clusters through minetweaker. Wiki Page

Copy this code in TechgunsOreClusters.json and save it to your_minecraft_folder/config/cofh/world/TechgunsOreClusters.json
