This is a land where the 3D effect is created at Blender using a texture of a elevation map (in white and black) with the modifier Displacement (strength = 0.2).
Is there a tool to make those elevations tips more soft, as a real mountain, instead each mountain be a lot of “tips” as the image?
Either you put your strength down… until you meet the “original scale”
or you play with the image settings like for example Brightness or Contrast maybe even Sampling…
or the ColorSpace should even be linear / non-color
