Script MaterialSwitch.cs

Hello guys,

I found the script MaterialSwitch.cs in the Vuforia Unity Samples at advanced model targets application.

That script is attached to the KTM bike model in Unity. I don't know what this script does and when it is called cuz

it has no start / update function.

Can some1 help me understand what this script does and when it is called.

Thnx
