Sorry to be a nag about this (I'm just trying to help, honest!)  but you did not say whether you tried using the Main camera. You only said "all camera angles". Did you really mean "all cameras"?

The symptoms you describe are exactly the same for me with all orthographic cameras, but not if I use the Main camera. With the Main camera (and the other perspective cameras, such as Dolly, Posing and Face) increasing the hither distance always solves the problem for me.

Sorry again to press you, I just want to make sure we're covering "all angels" (without wings)!
