This is some custom brushes crated by Worldmachine.

You can use this in your Minecraft maps, but never sell that maps or use them on a server.

You are only allowed to share or upload these maps if you will credit me and put a link to my PMC (Planet Minecraft).
I also have to ask you if you can let me know if you'll make map using these brushes, please. ;)

Hope you'll enyoy them, and good luck with terraforming! :D
