Crater

This filter makes a crater-like depression in the Minecraft surface. The selection box needs to be deeper than the radius of the crater or odd things happen in the middle of the crater. I left this in just in case you like odd things.
Suggested by SmeltScape on YouTube.
If you want a more tapered crater, use Flylands and discard the island.
