So apparently there’s not really a secret sauce to Minecraft worldgen, it’s just a lot of really big json files, a ton of splines, and there’s … Tolerable documentation on the wiki about it.
Or so I thought, until I got to the bottom of the files, and saw a function called old_blended_noise… Even the wiki doesn’t know how it works, so the trail is cold. Another algorithm gets away scot-free.
Edit: also I haven’t been able to trace weirdness or the resulting PV value it generates either.
right, yeah I ended up figuring it out. This stuff has multiple names, weirdness is ridges and PV is ridges_folded
