# Materials, Surfaces, and Textures

For convincing material rendering, combine four properties:

```text
[base material] + [finish] + [condition] + [light interaction]
```

Example: `blackened steel, satin finish, worn silver at exposed edges, broad cool reflections and tiny rust freckles around bolts`.
