I have an idea for the Mesa Bryce heightmap. Instead of two noises we use 3. 2 do the same thing as what you said before, but if the third noise is lower than the first noise then even if the second noise is greater, the first noise will be used. This way the "pillars" should be further appart from each other. Do you think it could work?
Excuse my poor drawing skills. It's on a touch pad.
