Use the Plus Minus Average utility

Use this utility to add, subtract, or average values in a given list of input attributes. The Plus Minus Average utility has three parts—two or more input attributes, an operator that you apply to these input attributes, and an output attribute that holds the result of the operation.

For a description of the Plus Minus Average utility attributes, see Plus Minus Average.

To create a plusMinusAverage utility node

1. Do any of the following:
   • Find this utility in the Create tab of the Hypershade window (under Utilities).
   • See Create a node in the Node Editor.

Once created, you can make several connections to the same attribute using Plus Minus Average based on a number. The last part of the attribute name has a number within square brackets.

Input 3D[0] designates the first connection to the Input 3D attribute, Input 3D[1] designates the second connection to this attribute, Input 3D[2] designates the third connection to this attribute, and so on. The first connection is always assigned a 0. Each connection gets its own ID number. For example, the OutColor of Stucco consists of one group of three values that you can connect to the Input3D values, not the Input 2D values or Input 1D values.

Tip: You can rearrange connections to a higher or a lower number without interfering with the other connections in the list, and you can break connections as you would any connection.
