Shadows wont show in scenecapture2D

I am new to UE4 this year and I require advice from experienced users, please. I already understand that the size of the scenecapture2D can cause the shadows to not show, but I have experimented with 1x1x1, less than 1x1x1, 10x10x10 and 100x100x100, yet none of this has resolved the issue. Could there be any other reason for cause to the shadows not showing in the scenecapture2D camera screen? The shadows are showing in the main screen. It is a night environment drone flight with spot light through a pine forest game. The tree shadows are moving with the spotlight in the main screen, but in the camera screen there is only the spot light and no shadows.
