# $reflectivity

**`$reflectivity`** overrides a [VTF](https://noskill.gitbook.io/titanfall2/documentation/textures/valve-texture-format-vtf) file's embedded reflectivity value. It tells [VRAD](https://developer.valvesoftware.com/wiki/VRAD) how much light should be bounced off the material, without affecting how much it receives.

{% hint style="info" %}
$reflectivity only affects [static light](https://developer.valvesoftware.com/wiki/Static_light).
{% endhint %}

### Usage

```
$reflectivity "[.5 .5 .5]"            //To bounce 50% of received light
$reflectivity "[0.75 0.75 0.75]"      //To bounce 75% of received light
```

The value is a [material vector](https://developer.valvesoftware.com/wiki/Material_vector), representing a [RGB vec](https://noskill.gitbook.io/titanfall2/documentation/colors#vec) color value.
