Hi! I had a question about the mc terrain generation as far as i know the terrain renders per chunk, from y=0 to y=256 so if you fly around the world each chunk that is generated goes from 0 to 256 Is it possible to edit the terrain generation so you can make a world 2000 blocks deep, but it only generates the first 200 blocks, and if you go deeper it generates a new 200 blocks deeper. does the world.dat support a 2000 deep block world, or even deeper? how crazy can i go with this? I never made a mod for minecraft but i think i have a pretty good idea so i want to accept the challenge and try make a mod. but i think this is pretty hard to edit the full terrain generation Sorry for my bad english, thanks for help! - Blacksun1998
