Vray 3 to Vray 2 Camera Problems

[Aaronrtw]

When I merged a camera that was created in Max with Vray 3 into a Max scene that has Vray 2 installed I found a couple of problems, 1) after a while the camera would disappear from the scene/unable to select in viewport however I could select the camera in the Select by Name menu, and 2) whenever I set a viewport to look through said camera nothing would show up in the viewport or in the frame buffer when rendered.. Is there a way to get around this problem without having to manually created a Vray 2 camera and match it to the Vray 3? Thanks!

Thank you for the feedback.
Can you send us sample scene with already corrupted camera?
Can you also tell us in few steps how to reproduce this?
Tell us which are the exact versions of V-Ray 2 and 3?
