There are many explanations out there that tell you to set the SerializeField by dragging and dropping it on the UI, but if you know that there is only one OVRCameraRig in the scene, you can find it, and if there is only one main camera in the scene to begin with, you can just use Camera. main. main] is fine if there is only one camera in the scene.
cs
[SerializeField]
GameObject camera;
void Start () {
if (!camera)
{
camera = GameObject.Find("OVRCameraRig");
}
}
It is a waste of time to reuse a script, forget to set a reference to a field, and then die at runtime with an exception.
