Outline

About

This outline post process shader has been created in Unreal Engine. The shader is interactive through exposed material parameters, which allow the developer to modify various properties.

Outline parameters:

• Dilated Convolution: Dilates the edge detection method, creating a thicker edge line. A value over 5 may cause unwanted artefacts.
• Threshold: Controls the outline appearance. A higher value will cause the edge detection to define the outline more, thus preventing it from creating unwanted artefacts.
• Fade: Controls the distance at which the edge detection will stop calculating and fade out.
• Color: Controls the color of the outline.
• Disable Colors: Turns everything in the viewport black, except for the outline.
• Invert Colors: Inverts the viewport colors, turning the black background into a white background. This only works if the [Disable Colors] parameter has been enabled.
