What comes out for each value that goes in

Clamp Density

Restricts a density to an inclusive numeric range.

density.clamp

What it does

Flatten the tallest parts of a height field without changing its lower slopes. Clamp stops values at the bounds you choose, so a peak that reaches the upper bound becomes a plateau.

Try noise in Input and lower Maximum while watching the preview. Clamp the noise before scaling it into a height. Use Remap when you want to stretch the whole range instead of flattening its ends.

On noise

The standard noise stretched to run from -1 to 1, before and after this node. First along one line, then seen from above.

The standard noise run through this node, rising from flat to full strength. Drag to look around.Noise from

Inputs and outputs

Name	Type	Default	What it changes
Inputs
Input	Density		The density whose extreme values you want to stop.
Minimum	Real	-1.0	Raises every value below this lower bound to the bound.
Maximum	Real	1.0	Lowers every value above this upper bound to the bound.
Output
Output	Density		The bounded density; values already inside the bounds stay unchanged.

Good to know

Keep the bounds in order

Keep Minimum below or equal to Maximum. Bringing them together makes the output constant.
