I'm trying to create my own SkyBlock map for 1.14 Minecraft but I'm struggling. I am able to create an empty overworld map, but that's not the problem. But how do I create an empty Nether and an empty end? I often read MCEdit could do this, others wrote that MCEdit would work for stuff like that. Do you guys have any hint or idea on how to accomplish this?
Ilmango recently started a new 1.14 Skyblock series and provided an instructional video along with a full set of tools (links in the video description) to create the entirely empty world (including Nether and End) and adding some tweaks that allow to obtain/produce some resources that would otherwise be unavailable.
(The entire process is rather lengthy and convoluted never mind impossible to perform without the tools linked, so I see no point describing what's in the video here)
