well its beyond me..but someone like lamb and the rest they would know if it is possible.
mainly for sea maps and bigger land masses is wat im seeing for a sea "..land and build.."but yeah 4x4 is kinda small for such a thing.
it looks like it has to be 128x256 etc i was crashing making a map messing with height .
it would be great if the pud could doit as it would put the map into the mini correctly..but i doubt its programmed for it.
cancelled for me ..it seems to just break the game..
where the objects are its still is fixed..and it wont let me add ..so it looks like one would have to reprogram the game
