Question / suggestion

[_]

MapMagic2 is now a free to use tool.
It implements some very fast noise.

Seems like this could actually realise the entire globes on per seed level.
Just throwing it out there Jon, He has an alpha Whittaker implementation fwiw but it feels like your biomes output would just "plug in" to a graph apiece.

I also recognise it's been years and you are probably doing something entirely else.
