Map Constant

Map Constant is one value as a map. Use it where a map setup needs a fixed number, such as the A of a Map Blend, or to share one number between several parameters so it is changed in one place. Mapping covers the idea.

It has no inputs, and one output that goes into another map node or is picked by a parameter's map button (Pick from network…).

Settings

The value is the number in the field times the multiplier on the menu beside it: 1, 10 or 100, or 45, 90, 137.5 or 180 for angles. The heading above shows the result.

A new Map Constant has the multiplier on 10, so its value is 10 until you set it to 1.

The field has its own map button, so the constant can itself be driven by another map.

Status

Map Constant is experimental. This page describes Map Constant 2.0, the one in the Tab menu. The older 1.0, with a chain input and a Blend Mode, is hidden; on load, a 1.0 in an old scene becomes a 2.0, with a Map Blend in its old blend mode if it was chained to another map (a chain on replace is dropped). The Map Constant entry the Natsura toolbar offers with a map selected still places a 1.0, so place it from the Tab menu.
