Camera Correction

[Bullit]

Any option to correct camera and make the vertical lines of objects vertical?

If you mean something like Camera Correction modifier, I think the option in SI is to align camera and interest along Y axis, this makes vertical lines aligned. Then, enable projection plane in camera ppg, move 'optical shift', slghtly along Y, to get usual 'look at up' view. Not sure is it the exactly same result as Max modifier.
