Bump Offset and Parallax Occlusion Mapping - UE4 Materials 101 - Episode 8

Here we discuss two techniques for improving surface shapes beyond normal mapping. Both techniques use a height map to more clearly define the shape of the surface. Bump Offset mapping adjusts the UV coordinates of the surface based on the view angle and depending on the height map. It's a fairly cheap technique, but doesn't work well at glancing angles. Parallax Occlusion Mapping traces rays to recreate the surface shape. It's a more robust technique that works at glancing angles - but it can also be significantly more expensive. This video shows how to set up both techniques.
