The plugin provides some examples, here's an explanation of how they work.
Explanations will be expanded on further at a later date.
Example 1
A simple 2 coloured outline consisting of smaller black lines at regular intervals.
Example 2
3 coloured effect where the outer and inner colour move.
Example 3
A distortion effect where the distance field is treated like a height map, that offsets the background.
Example 4
A dual effect with diagonal lines moving from left to right and a standard outline with coloured stencil.
Example 5
A neon glow effect where teh distance field is used to create the glow rather than using the built in bloom.
Simple Outline Base
A basic example material shows you how to change the outline size, whether it's just the inside, outside or both. It shows you how to have a different colour for both the stencil and any occlusion.
