# Vector Gain

> **Note:** **What is it about?**
>
> This page describes the **Vector Gain node** of the Redshift renderer in **Cinema 4D**. It applies contrast gain to each vector component using its matching gain value — per-axis contrast shaping of vector data.

Returns a contrast gain of *Input* by *Gain*, using the following Ken Perlin formula:

Bias( 2 \* *Input* - *Gain* ) \* 0.5 ; if Input \< 0.5

1 - Bias( 2 - 2 \* *Input* - *Gain* ) \* 0.5 ; otherwise

*Gain* and *Input* components should be in the range between 0.0 and 1.0
