Shader: Noise Tex Outline

About
 

This 2D alpha outline shader has been created in Unreal Engine. It is an easy and efficient way of getting the outline of a noise texture or an icon, due to the fact that it doesn't rely on as many instructions as the sobel edge function. The shader is interactive through exposed material parameters, which allow the developer to modify various properties.

​

Parameters:

• Alpha: Allows the user to select the alpha mask texture to detect the border.

• Border Size: Controls the width of the effect.
