--- title: "Materials, textures, and shaders" framework: realitykit role: collectionGroup role_heading: API Collection path: realitykit/scene-content-materials-and-shaders --- # Materials, textures, and shaders Apply textures to the surface of your scene’s 3D objects to give each object a unique appearance. ## Overview Overview Materials define the appearance of 3D models in RealityKit, by defining how their surfaces interact with light. Materials can also occlude objects behind them, hold shaders, or act as portals to view other worlds with PortalMaterial. RealityKit includes a few material types to help you get started, including SimpleMaterial for basic color and textures, and PhysicallyBasedMaterial for realistic lighting effects such as reflections, roughness, and emission. ## Topics ### Simple materials -
