Scale Density

Multiplies a density input by a constant factor.

What it does

Make hills higher without making them wider. Scale multiplies density values, so a subtle noise can become a height field measured in blocks.

Connect your noise to Input and increase Factor until the relief has the height you want. Keep the noise’s own scale for hill width. A negative factor reverses the pattern, turning its high areas into low ones.
