# intensityExponent

The intensity value of the light, defined on a logarithmic scale.

```
var intensityExponent: Float
```

## Discussion

An intensity factor is computed as
`2^intensityExponent`.
The computed value modulates the native value specified in the
diffuse and specular textures.

Set the intensity to `0` to result in a scale factor of `1`.
This uses the unmodified texture’s diffuse and specular intensities.
