what is this???
It's a program that generates insanely brick-efficient cubescapes from heightmaps. These generated builds are exported as a save file, so that you can load the file on any server you go to.
Heightmaps are basically just grayscale images that represent elevation levels - the more white in an area, the higher its elevation. Therefore, black areas have low elevation.
The screenshot I posted was an awkward angle of one of these cubescapes. Remember, this wasn't designed as another image2brick. This one was designed for creatin terrains.
