Perspective match don't work with Arnold...

I have attached a file if anyone can test it and

find an alternative solution to this problem:

I assign a background image (as environment map and

viewport background map) with of course the same

aspect ratio in render setup.

I create a free camera and then I initiate perspective match

from helpers tab.

I setup vanishing lines, so I can see on my viewport my model

inserted correctly over my photo.

As you see for ex scanline renderer, renders it correctly, but arnold

has a different opinion...

test-perspective.zip

Anyone can give a solution to this, or an alternative way

to do it?

Thanks always.

I think it has to do with the fact that the camera was scaled.

If I reset the scaling, it renders the same as the viewport.

Hi, I hace the same problem, the render appears way up that it should be.

I try applying a "reset x form" to the camera but the problem persist

and also tried reseting the scale by clicking with the rigtht buttom, but that screws the position of the camera..

Can you share How can I reset the scaling so it renders correctly? I havent found a way.

Thanks a lot.

@Eduardo Ramirez

Select camera and go to->select and uniform scale

Put value 1 in offset screen and press enter.

Repeat entering 1 (follwing by enter) till all x,y,z are zero.

Try to render, it should be ok...
