Thank you !......, i have not seen the 0.0.

Hi! If you go to 6:10, you'll notice the lens shift is set to 0.0, its default. This is why the building in the render is tapered. To fix this you right click on the lens shift button at 8:26 and V-ray guesses the lens shift correction based upon the view you set. At 8.51 you can see the value was changed to 0.3150. Good luck!
