Works here, but yes the Test Scene as provided is set to use the Standard render, and not Corona. So, if I hit Render with the scene loaded "as is", I get a render with no shadows in the Picture Viewer, as it is using the Standard renderer and can't process the Corona Lights. If I start IR with the scene "as is" (having opened the Corona VFB), then I get a render there with shadows, which is kind of interesting since Corona isn't set as the render engine.
If I set Corona as the render engine, both IR and offline render show as expected in both VFB and PV.
