Ah okay. . .
I noticed that no matter how small the number you subtract, a minimum value of 1/256 is subtracted. Same for adding - it's just a case of how blitz rounds the number that decided why the ADD fraction has to be greater than 1/256 and the SUBTRACT fraction can be less.
I thought you could modify a terrain's height to any value from 0-1.
Now it seems it will only accept the 256 different values. . .
I wonder if this is only true if you load the terrain from a bitmap - could a 'created' new terrain allow a more continuous set of values. . . hmmm.
