Map Random

Map Random gives each element of the tree its own random value between Min and Max. The values are stable: the same element gets the same value every time the tree cooks. Use it to break up a parameter that would otherwise be uniform, such as branch angle or length. Mapping covers the idea.

It reads each element's random attribute, so nothing needs wiring in; its five inputs (Input, In Min, In Max, Out Min, Out Max) are unused. Its output goes into another map node, such as the B of a Map Blend to add a random spread on top of a base, or is picked by a parameter's map button (Pick from network…).

Settings

Min and Max set the range, 0 to 1 by default. Ramp shapes the distribution before the range is applied: a ramp that stays low for most of its length makes most values land near Min, with a few near Max.

For a smooth variation through space rather than a separate value per element, use a Noise Effector.

Status

Map Random is experimental.
