How to enable Camera Shake in VR

Want to trigger camera shake in VIVE.
Tried creating empty game object and assigning a script but not working.
Any other alternative??

First, I don’t think adding a camera shake in VR is a good idea, unless you want your users to puke on the ground.
If you absolutely want to do it, apply the shake script to a parent object of your VR camera, and it should do the trick.
