# MDLMaterialSemantic.displacementScale

The scaling factor for displacement of a material’s surface.

```
case displacementScale
```

## Discussion

Model I/O uses this semantic for the `objectDisplacementScale` and `map_objectDisplacementScale` attributes when importing from the MTL file format (for assets in the OBJ file format).
