I Accidentally Found Something Huge in Unreal Engine 5
Can a single flat plane in Unreal Engine 5 create displacement-like depth that reacts to Lumen and multiple dynamic lights? While investigating Parallax Occlusion Mapping (POM) and Pixel Depth Offset, I modified part of the engine source and discovered an unexpected real-time lighting result. In this experiment, I compare it with standard POM, inspect the geometry in Wireframe Mode, rotate the Directional Light, add Spotlights and Point Lights, and test how the effect responds to different Lumen scalability settings. This is not part of the current Implicit Heightfield Projection(IHP) plugin, but it could become the foundation of IHP Plus. If you understand Unreal Engine materials and rendering, tell me: am I exaggerating, or is this actually huge?
