Camera settings aren't affecting interactive render

[just8thedog]

I signed up for a 3ds max corona course and after importing fbx files from Revit and applying an override material to everything and an HDRI sky environment, and corona camera, When I open the interactive renderer, the only camera setting that affects the interactive render is field of view.
Adjusting shutter speed, iso, and F stop does nothing. I can increase the HDRI output to brighten or darken the image. But the camera settings are doing nothing. Anyone know what I might be missing? I should also mention I have set up a camera viewport and that is the active viewport I am trying to render from.
Thank You

Most probably you need to add the "Photographic Exposure" operator to the VFB tone mapping stack.
