Bias scalar

The Bias scalar node creates a curve, the shape of which depends on the Bias value. The output of the node is the value of the bias curve corresponding to the Input value. Here's a graph showing the bias curve at two different Bias values:

 

The output value will be between 0 and 1. The node expects both the Input and Bias values to be between 0 and 1. It does clamp these values to make sure that they are within that range.
