Are we allowed to use this mod? It's not a xray mod and the mod only works if you're 10 meters from the ore. http://minecraftsix.com/scenter-mod/
So it's a low range 3-dimensional radar? I would still consider it cheating. I also don't like how it "feels". I haven't taken the time in my life to learn how diamond and iron ore smell and how they smell different. That being said, it'd be interesting if the mcMMO mining had a perk like that after a certain point.
This is not allowed. Kind of common sense to a point. It's a mod that shows you how close you are to an ore and in the direction it is in 10/10 would be considered cheating
