So my team is looking into replicating a sort of effect similar to that of “The Taken” in Alan Wake. The effect is essentially a blurry/glitch sort of silhouette, an effect we wish to achieve on enemy faces in our game. I’m at a bit of a loss as to how to make something similar, maybe one of you glorious chaps has an idea?
This is a combination of effects. Your idea of having distorted particles is good. Plus added black smoke effect spawned on the mesh itself. To get the distorted silhouette you could render the characters to the custom depth and use a distorted version of it post processing effect.
Adding to Roel’s comment, you can do a lot by manipulating the UV’s of your Custom Depth Pass. Here is an example project with the Standard UE4 Guy rendered entirely as a custom depth “Shadow”
