Cameras do not match in Keyshot and 3dsMax

[Justin M]

Windows 7
Keyshot 5.2.1
3dsmax 2015


I've rendered out a scene in KS, and I have to comp in something in post because KS does not support animation deformers. My problem is the cameras do not match. I've exported from 3dsmax to .FBX, all the object animation came in fine, the camera is animated, I have the same FOV on both the cameras in max and keyshot. They are just slightly off making it literally impossible to comp things in post.

I've done this before and comped in things just fine. Did something happen in the latest update?
