Generate 3D models of controllers

Hello,

I am now using a range of virtual reality tools in Unity, and I would like to be able to use Oculus asset to generate 3D models of controllers.

However, I can't use the OVRManager script since it interacts directly with the camera. But when the latter is not present the controllers do not appear, what would be the easiest way to make the controllers active without going through this script?
