Hello friends,

I have downloaded a custom map from this website (planetminecraft), and was planning on using it for a survival server. The problem I am facing is the following:

The caves, ores, and dungeons are not the same as a normal survival world, which I would like them to be. There are significantly less ores, no monster spawners (dungeons), and really big and unnormal caves. I would like to have the actual map biome and environment, but normal ores/caves.

Could someone please tell me either how to do this or help me with it?

Much appreciated! :D
