        Actually, Performer calculates every normal regardless of how you specify
its shading flags. You can tell performer to not calculate the normals of
an entire database, but this leads to problems in our program: much of our
collision detection routines rely heavily on precomputed vertex normals, so...
    What we need is a way to tell performer to keep the normals, and just
not use them to calculate shading...without having to write our own loader.
Can this be done?
