View through a 3D window should show a 2D background but shows DAZ Dome instead

View through a 3D window should show a 2D background but shows DAZ Dome instead. I am using the latest Public Beta .366
Renderer is iRay. Dome and Scene. Background - 2D image loaded chosen to show in render.
I thought the problem was the godrays made out of a DAZ primitive cube per SickleYield's tutorial but it is not.
I've tried changing the 'Window Seat Alcove' window glass material to several different iRay presets for glass from the DAZ Uber iRay glass preset freebies, to MECH4D's, to other glass presets included with the 'Window Seat Alcove' scene and none of them have worked.
I'm at a loss now as to what I need to change in the render setting or the scene material settings to fix this.

Is this working in the release build then?
No, but it is the godray DAZ Primitive cube I made I found out. A couple times it worked in same scene but not anymore so it must be some combination of materials. I noticed in a scene i rendered a couple of weeks ago, looking outside of a castle window, it caused the church yard to be magnified closer and shifted left.
Thanks though.
