Vector Gain

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
