Bias Scalar
Overview
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.
Settings:
- Name: This setting allows you to apply a descriptive name to the node, which can be helpful when using multiple Bias scalar nodes in a project.
- Enable: When checked, the node is active, and when unchecked the node is ignored.
- Bias: The value defining the shape of the bias curve, as in the graph above.
Error conditions:
- It is an error for there to be no Input value. In that case 0 is output from the node.
- It is an error for there to be no Bias value. In this case the Input value will be output.
Fun with Bias Scalar
The following examples show how the Bias scalar node can be used to modify the output of a node.
The image below shows the effect of the Bias scalar node on a radial gradient, as the Bias value changes from 0 to 1.

The images below illustrate the effect of the Bias scalar node on the three different Edge profiles, Smooth step, Bevel, and Radial, of the Simple shape shader.
