Information

Outline is a post process material for Unreal Engine that draws visible lines around the edges of objects in the scene. It works well for making characters or props stand out more clearly, adding a comic-like edge to the image, highlighting silhouettes, or giving the scene a more drawn and graphic look.

Material Parameters

Dilated Convolution:
Dilates the edge detection method, creating a thicker edge line. A value over 5 may cause unwanted artifacts.
Threshold:
Controls the outline appearance. A higher value will cause the edge detection to define the outline more, thus preventing it from creating unwanted artifacts.
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.
