Steam VR shader issues: meshes dissapear / don't render

Unity Engine
1

I’m using the Lab Renderer and the SteamVR plugin. If I convert from standard shaders to vr_standard from the Lab Render the meshes disappear. Sorry if this is a bit vague. I’m not entirely sure where to even start debugging this. My google search seems to be fruitless, Valve doesn’t seem to have a very well organized forum for support on the plugin?

This is happening in the editor and headset.
Unity 2017.1
Steam VR: 1.2.2
Lab Render 1.0

You need to have the Valve Camera script attachted to a camera.
