# Materials (landing)

- "Materials in Unreal Engine define the surface properties of the objects in your scene" — "paint" applied to a mesh; tell the render engine "exactly how a surface should interact with the light"; inputs from textures and node-based Material expressions plus Material property settings.
- Material Instances: hierarchical relationships alter child materials "without recompiling the shader". Material Functions: package parts of a graph into a reusable node. Layered Materials. Substrate Material Framework listed as a separate topic.
- Material Properties page (material-properties-in-unreal-engine) redirected to the docs home page and could not be fetched.
