Hi, I’m trying to replicate what I see in my camera in real life with the isaac sim camera model. I’m having difficulties getting the same FOV and I’m not sure what other parameter I can modify. Currently I create a camera with 8mm focal length (real lens focal length) and close to 6.5mm horizontal aperture (real sensor horizontal size). I see that the focal length is in tenths of a scene unit according to the documentation but when I test different stage units by setting it first at 0.1 and a camera with focal length 8 and then I set the stage units at 1 and create a camera with focal length of 8 again I get the same image from the camera views, shouldn’t it be different since a tenth of 1 gives something eles than 0.1 and that would change focal length?
Why can’t I get a similar view if I’m using the “same” real parameters, Should I select a different camera model? Do I have the concept of aperture wrong?
