What comes out for each value that goes in

Remap Density

Linearly maps one density range into another.

What it does

Turn a noise pattern into a useful blend or height control without changing where its features lie. Remap stretches and shifts its values along a straight line.

Set Source minimum and Source maximum to the input values you want to map, then choose their destinations with Target minimum and Target maximum. Try it before Mix to make a mask. Reverse the destination values if the opposite regions should stand out.

Inputs and outputs

Name	Type	Default	What it changes
Inputs
Input	Density		The density to stretch and shift.
Source minimum	Real	-1.0	The lower input reference, mapped to the first destination value.
Source maximum	Real	1.0	The upper input reference, mapped to the second destination value.
Target minimum	Real	0.0	The output value at the lower input reference.
Target maximum	Real	1.0	The output value at the upper input reference.
Output
Output	Density		The remapped density, continuing beyond the reference values.

Good to know

Clamp a mask when needed

Remap keeps going beyond its reference points. Add Clamp when the next node needs a mask that cannot pass those bounds.
