I host a multiplayer creative server and the current height limit is really low. Probably 64.
I was wondering if there is a way to increase this height limit without deleting the map itself. We have already made
cool things on the server, but we want to make big skyscrapers, without losing our creations.
The simplest way to do this would be to just use OMEN. It has a utility for resizing the map along the Y axis, it just adds empty space at the top and bottom. Make sure the map's in a .dat format though, so you'll probably have to dump it from a client...
