**Component Mix Vector**[edit]

**Node Description & Purpose: **

This node is used to blend or interpolate between the two input values. Unlike the normal Mix vector node, the Component mix vector node takes a vector as its **Mix controller** and allows you to individually mix the components of the input vectors. That means you can have different mix values for the X, Y and Z components:

Output.x = Input.x **and** Input 2.x **mixed by** Mix controller.x

Output.y = Input.y **and** Input 2.y **mixed by** Mix controller.y

Output.x = Input.z **and** Input 2.z **mixed by** Mix controller.z

The inputs are mixed using linear interpolation. If the mix value is 0 then the **Input** value will be output. If the mix value is 1 then the **Input 2** value will be output. If the mix value is between 0 and 1 then the output will be a blended combination of the two input values.**Node Type: ** Function**Settings: **

**Input 2**: This is where you specify the node for the Input 2 value.**Mix controller**: This is where you specify the node that is used to control the mixing between the Input and Input 2 values. If you do not specify a mix controller a value of 0.5 is used to mix each component of the input vectors.

**Error conditions**

- It is an error for there to be no
**Input**value. In this the output vector will have all its components set to 0. - It is an error for there to be no
**Input 2**value. In this case the**Input**value is output. - If there is no
**Mix controller**node attached then a value of 0.5 is used to mix each component of the input vectors.

A vector is a set of three scalars, normally representing X, Y and Z coordinates. It also commonly represents rotation, where the values are pitch, heading and bank.
