thanks for the fast answer. As a beginner i hope i did understand right.

So, when i try to import a heightmap of the size i mentioned above, i have to use these values from starting area position x,z 0 :

x: 0

x: 32000 ( 2048km / 64 m )

z: 0

z: 32000( same math )

maxY: 5000 ( is it right thats the value for the max height of "montains"? If yes, what happens to heigths above this value? )

ok i tried this out and as i expected, this data is too large

, i get an error message 'cant allocate 65536 bytes of memory'.

What is the max value you can import a heightmap?

thanks
