Convolution Shader
About
This convolution 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.
Convolution parameters:
Left, Top, Right, Bottom and Center: Kernels that determines the image processing operation.
Dilated Convolution: Dilates the edge detection method, creating a thicker edge line. A value over 5 may cause unwanted artefacts.
Fade: Controls the distance at which the convolution will stop calculating and fade out.
Disable Colors: Turns everything in the viewport black, except for the outline. The outline will appear black or white based on your [Left], [Top], [Right], [Bottom] and [Center] parameter values.
This post process shader works in both Unreal Engine 4 and Unreal Engine 5. Installation guide is included.
