This effect is based in UE4's material system, utilizing a custom material function to burn out and disintegrate objects along a user defined opacity mask. It features emissive edges, which the user can change in both color, brightness and thickness, as well as parameterization of all other basic material options such as color/texture, normals, etc. The goal was to allow for maximum flexibility to create a wide range of visual styles and outputs from a single parent material.
