please click on ''it worked'' if you found this tutorial useful:))
firstly sure perspective is actived
then go to view>>modify>>perspective
you can make your choice between 0.1 and 1000. 3 writes recomended here. I use 0.5 usually
click on ok and you will see the perspective changed
render with perspective scale 100 (it is bad)
render with perspective scale 0.5 :)) it is perfect!
