when reading this i wasnt sure what it meant, so i figured id just try it and see what happens.
Change your heights from -x 750 to -x 850 and -n -69 to -n 69
it didnt take away the stepy lines, and took away the water on my map... which tbh is wat i expected to happen.
Problem solved. From my explaination on how to fix it should be pretty obvious what the problem was.
and
use lowpass. Thos are shadow lines because the light is hitting bumps in your terrain and shadowing every spot. Lowpass will fix that.
i have 2 ideas but i dont think either of them were right...
you suggest that stretching the map out (-x750 to -x850) will solve it, meaning that my map is too flat so the shadow lines are noticable
or
removing the water (-n -69 to -n 69) might be required for lowpass to work...
maybe im just missing something here, but thanks for the help anyways.
