Daydream Controller cursor going through colliders

Ther is a quality requirement that says:

I thought it can be done by adding colliders to objects, but it still renders it behind them. How did you solve it?

 

Do you have the GvrEventSystem prefab and the script GvrPointerPhysicsRaycaster in your scene?

Thanks,

Dan

 

I have GvrEventSystem prefab in my scene, but I can't find GvrPointerPhysicsRaycaster script. I also can't find it in the GoogleVR folder. Do you know where I can find it?
Edit: Never mind, found it, everything works now. Thanks!
