I am actually trying to create on my server a superflat world like in singleplayer: A layer of grass/dirt, then 3 layers of dirt and nothing but cobble until the end.
The only thing I succeded on doing was the
/mv create WorldName NORMAL -t flat but I still have villages, some slimes, and the worst: no control over the layers (what if I wanted a desert 5 layers of sand, 20 of cobble...).
There must be an easy way that I am not finding (all I found was a totally empty world with just 1 cube to build around...)
I also tried to create a world on singleplayer and copy the file from
%appdata%/.minecraft to my server folder, but ended up with a strange (but fun) world...
Do you know a solution?
