Summary:
I put the GvrControllerPointer prefab into my scene, as a sibling of Main Camera. But when I hit play, the pointer does not show up! I get a bunch of this warning "No GvrEditorEmulator instance was found in your scene. Please ensure thatGvrEditorEmulator exists in your scene.
UnityEngine.Debug:LogWarning(Object)" although it is right in the scene. I don't know if this affects the problem.
I just tested on my Mac. I haven't put it in a phone.

Found using:

• Google VR SDK version: 1.120.0
• Unity version:2017.3.1f1
• Phone manufacturer, model, and O/S version: not using a phone
• Viewer manufacturer & model:not using a viewer

Steps to reproduce the issue:

1. Have a scene and drag GvrControllerPointer in
2. Hit play. No pointer shows up...
