# intensityExponent

The intensity value for the resource, which RealityKit defines on a logarithmic scale.

## Declaration

```swift
var intensityExponent: Float
```

## Discussion

Discussion RealityKit multiplies the intensity of the probe by 2^intensityExponent. An intensityExponent of 0.0 means using the diffuse and specular intensities as-is.
