This MCEdit filter will create redstone wires (busses) for you automatically. Just place a start point and an end point, and any guides that you want, and it'll try to find a path. It even places repeaters for you.
SkyGrid is a challenging survival map for Minecraft in the style of SkyBlock. It's formed out of a grid of random environmental blocks, with a gridlength of 4 meters. There are no rules, make whatever goals you want. Try and find the random chests and spawners placed throughout the map!
With this filter, you can control, down to the individual x/z coordinate, the biomes in your map. Useful for stopping mob spawns or rain/snow, or even putting a bit of nether or End into your main world.
