I was recently asked to create some worlds for a school. I started searching for tools to help me build the world so I don't have to build brick by brick. First thing I did was download MCEdit 2 and I tried to see if it could read .mcworld files. Turns out it can't load them, then I found out .mcworld is just a zip with a changed extension. So I unzipped and tried to load the level.dat that was inside. Nothing shows up, no blocks or anything. Then I tried taking a world from Minecraft Java edition and zipping it up and changing the extension to .mcworld. I imported the file into MC:EE and unfortunately every world I tried gives me the same one world in MC:EE (You start on an island next to a bigger land mass). I also tried to open the MC:EE world in MCEdit Unified. It also thought the world is blank and asked me if I wanted to rebuild it. I couldn't find any other useful tool on Google. These forums didn't have too much on MC:EE, I was mostly looking through posts talking about converting between MCPE and PC version.
Anyways to get to my question, does anyone know of a tool to create worlds for MC:EE similar to MCEdit?
