If you are using the latest EnergyPlus version 9.2, there is a new Construction:AirBoundary object that was added for this case of an "air wall" separating two zones from each other. Inputs here can specify how EnergyPlus calculates solar gains, inter-zone mixing airflow, and radiant heat exchange between the two zones across the surface using this air boundary construction.
This is easier and faster than the approach you've done in OpenStudio. The "Air Wall Material" you've added is an opaque Material object -- so no light will pass through unless you draw a window into that surface. You will also need to add Zone Cross Mixing object(s) to account for the inter-zone mixing airflow.
