-'''Node Description & Purpose: '''<br /> The Smooth step scalar node is a function node which can be used to create a smooth transition between values. It outputs a value between 0 and 1 depending on the '''Input''' value and the '''Step start''' and '''Step end''' values. The two step values define a range of values between which the output value is smoothly interpolated between 0 and 1. See the graph below for an idea of how the function works:<br /><br />

-<br /> When the '''Input''' value is less than the '''Step start''' value the output is 0.<br /> When the '''Input''' value is between the '''Step start''' and '''Step end''' values, it will be some smoothly interpolated value between 0 and 1.<br /> When the '''Input''' value is greater than the '''Step end''' value the output is 1.<br /><br /> The Smooth step scalar is very useful for creating smooth transitions between two values. Having smooth transitions is important when creating procedural textures and the like because sharp transitions (such as those created by the [[Hard Step Scalar|Hard step scalar node]]) can cause undesirable visual artifacts such as aliasing (otherwise known as "jaggies"), or popping of textures in animations. <br /><br />'''Node Type: '''Function<br /><br />'''Settings: '''<br />
