This is a utility that will destroy any chunk which is all air and has no Tile Entities (chests, signs, etc) and has no Entities (mobs, cows, armour stands, items, etc). Suggested by Qwertyuiopthepie
Select an area including the chunks you want to purge, run the filter, and save the result. You may need to reload the world (CTRL+R) to see the changes applied in MCEdit.
ALWAYS WORK WITH A BACKUP. While all care has been taken in the testing of this code, it is not using well documented APIs and you may damage your world.
v2 also purges chunks whose terrain is marked as "not populated" (i.e. the chunks around the very edge of the explored map).
v3 suppresses re-lighting the chunks in the selection area, so the save is very quick.
This filter Creates command blocks that cause one entity to orbit another.
v3 adds support for the orbiting entity to rotate while it orbits.
This filter creates cladding for certain blocks in your world.
v2 includes an 'invert' option, suggested by JsKingBoo and coded by martinhanzik on this Reddit thread: http://redd.it/2p1hp2
What it does is shown below (v1 behaviour):
Quick hack of BrianAwesomenes filter for note block / command block mapping. http://www.youtube.com/user/BrianAwesomenes
Originally I built this for Podshot and The Destruc7i0n. It re-organises command blocks and gives them a redstone block running track so you can trigger them in order. The original idea is from TwitchNitr0.
