1. Is there any plugin which can spawn random ores all over the map ?
     
  2. I believe Reneb has added additional commands to the Build plugin to allow you to spawn things like trees, plants, ores,...
    Code:
    - /plant ID => Plant a resource (barrel, trees, ores)
    The IDs you need would be 113 (metal), 114 (stone) and 115 (sulfur).
     
  3. Yes.... but! i want to spawn them all over the map

    /massore spawn "radius/all"
