"Destination array is not long enough" when trying to import 16 bit terrain data

Unity Engine
1

I have a raw terrain file that I exported from world machine, but when i try to import it as terrain it gives me this:

ArgumentException: Destination array is not long enough to copy all the items in the collection. Check array index and length.

It works if i import it as 8 bit, but then the terrain looks all terraced and gross. What’s going on and how do i fix this?

EDIT: For anyone that comes across this issue in the future, it was all caused because world machine exported it as .r16, just rename the file with .raw instead and it will work

Take your Unity-side terrain and export its heightmap as reference.

That’s gonna be how big the one from “world machine” will need to be.

I don’t get it, does unity just not allow you to use 16 bit terrain? Then why does it give you the option to use it?

Yes, you absolutely failed to read my post, that’s for sure.

Go back and read it because I said absolutely NOTHING like what your “summary” indicates.

Exported some random painted terrain from unity and its 2053kb, same as the terrain data i was trying to import. I can even import the exported terrain as 16 bit. I don’t understand what the problem is, can you help me without being snarky this time?
