You have two options, as far as I can see.

1) Use the "fisheye" camera with a 360 degree angle; this will give you a
circular image that can't be mapped to a sphere as-is with the standard
spherical projection (which is what I assume Max also uses). Rather, you
first have to convert it from polar coordinates to rectangular coordinates.
I know Photoshop has a filter to do this, not sure about other image
manipulation programs.

2) Get MegaPOV (http://nathan.kopp.com/) and use its spherical camera
projection (the MegaPOV manual documents its parameters). This will give you
a rectangular image that is directly mappable to a sphere with standard
spherical mapping.
