It looks like ImageMagick is having some issues with maintaining the 16 bit values, which is unfortunate. “Unholy amount of terracing” is definitely an accurate statement.
Thanks for the info - since I don’t have access to tiling options in World Machine, I’ll have to figure out a way of slicing the heightmap accordingly. Just to be sure - if I’m following along with the wiki, I’d have 4x4 tiles of size 2017. Since they’re sharing vertices, I’d end up with a large heightmap of (2016x4)+1=8065.
I should hopefully be able to use the crop tool in Photoshop, then - I kind of wish it were possible to automate the slicing, given the number of crops I’ll be making, but honestly I’ll take what I can get
