**Power Scalar**

**Node Description & Purpose: **

The Power family of nodes output the **Input** value raised to the power of the **Input 2** value:

Output = Input **to the power of** Input 2

For colours the calculation is done on a component-wise basis, for example:

Output.red = Input.red **to the power of** Input 2.red

Output.green = Input.green **to the power of** Input 2.green

Output.blue = Input.blue **to the power of** Input 2.blue**Node Type: ** Function**Settings: **

These nodes just have one other setting, which lets you choose a node for **Input 2**.
