Many mobile devices have significant hardware limitations compared with desktop hardware and game consoles, especially in terms of compatibility with graphics features. To address this, Unreal Engine has an alternate rendering path for mobile devices. This rendering path uses simplified or performance-oriented models for many of Unreal's rendering features, such as shadows and textures, and it removes many unsupported post-processes. The guides in this section provide details about configuration options and features in the mobile renderer.
