GUI.DrawTexture with OVR

I'm trying to apply a vignette effect of a helmet across the two rift cameras, but it is drawing the texture seemingly on a different layer to the cameras. I've tried attaching the vignette script/texture to each individual camera but the result is the same.

Has anyone come up with a solution to this or encountered this issue before?

I've included a picture to help show my problem:

    Any draw calls initiated within OnGUI will not be affected by post-processing effects applied on the rendertarget, because OnGUI is called only after the scene rendering stages have completed. GUI elements will not be affected by post-processing shaders. This is well documented. Here's a good wiki article that lets you explorer the Unity pipeline.

    If you want your helmet to be affected by the vignette shader, then it must be rendered as part of the scene.
