Elumens TruFrame and 3D Studio Max

Hello, as part of a project for university, I've been given a set of
instructions on how to make spherically correct content for an Elumens
hemispheric display we have. What needs to be done is that four
cameras are set in such angles with 90 degrees FOV in 3d Studio so
that when the output is stitched together with the TruFrame software
given by Elumens, you get a nice dome-y picture that looks great on
the actual display. My problem is that although when using the left
and right views the output is great, when the top and bottom views are
involved I get a head twisted a few meters away and feet missing (just
an example). I'm probably misinterpreting what the instructions mean
by rotate right etc... so if anyone's solved the problem I'd
appreciate the help.

thanx
