there is no solution - mine is to distort the image in PS by using two selections - but this is good when you have a relatively cube-shaped object (happily , this is the current case)
I select one facade and distort it and later the same with the second facade.
There is a nice solution in a software called ArtLAntis Render but it is not transfarable.
:-(
in 3DMax 6 there is a camera fixing utility and this one is somethibg I forgot to mention to Duncan Breansmead when I sent him a list. (upon his request) - hope he reads this one , too...
