Shadows not showing on scenecapture2D screen, but showing on main screen

I am creating a demo of a drone piloting through a pine forest in low lighting conditions with a movable spotlight. In the scene the trees have shadows tat move with the spotlight. However, in the scenecapture2D screen none of the tree shadows are showing at all. I am wanting the shadows to show in the camera screen, but no matter what I try I can never get the shadows to show. I am hoping that someone with experience will be able to help on this issue.
