On the bottom window, where the Parallax map is off, you can see that all the cavities keep visible until they rotate 90º away from the camera. Look at the rotating images on the side, on the top window where the Parallax map is on, pay attention to the middle wrinkle in the lower lip and see the cavity of that wrinkle “disappearing”, in fact being occluded as the model rotates. If you pay attention, the silhouette of the mesh doesn’t change. It helps to create a more realistic sense of depth to the skin since this map will take care of occlude the cavities that shouldn’t be seen from certain angles, this effect is called Parallax Occlusion.Īs you can see in the video above, when turned on, it looks like the mesh received an “inflate”, but in fact this is only the height map controlling what pixels should be seen and which ones should be hidden based on the angle of the camera. As I mentioned before, I added a Parallax Map to the skin Material.
