Constant Nodes

This plugin provides compact blueprint nodes for a variety of common mathematical and physical constants.

Easy to Read

Typing constant values directly into node text boxes, or setting up blueprint variables, is tedious, hard to read and error-prone. These easy-to-read compact nodes made constructing math and physics formulae a breeze. Take a look at the gallery for some examples of well known equations which are so much easier to understand when you can just read the common name of the constant, and not the numerical value.
