Parallax Mapping - Lumberyard User Guide

Parallax Mapping

Open 3D Engine (O3DE), the successor to Lumberyard, is now available in Developer Preview. Download O3DE or visit the AWS Game Tech blog to learn more.

Parallax occlusion mapping (POM) is an enhancement of the traditional parallax mapping technique that creates detail in a texture to add the illusion of depth. This depth perception changes based on perspective.

Parallax occlusion mapping (POM) and offset bump mapping (OBM) are similar to displacement mapping and tessellation, but their computational requirements are not as demanding. However, POM is not suitable in every situation. Use POM only for high-performance computers and OBM for devices such as consoles. When you use POM, you must enable both shader generation parameters. Lumberyard automatically defaults to OBM for setups that cannot run POM.
