Film and Stage Ruby for Sketchup and Vray conflicts

Hi,

I’m trying to design a virtual set using Sketchup and Vray. To do this, I need to set cameras in the exact positions as they will be in real life. I have installed the ruby script film and stage plugin and have inserted those cameras into the model. The angles are terrific.

The problem occurs when I render using VRay. The angle completely changes.

Is there a conflict here that is known about and is there a way to get things straight?
