Is it possible to get Solid Angle to add a focal length metadata key if it's not there? Or, as Ivan pointed out to me some time ago, a filmback width (haperture) may be better since that is fixed whereas focal may not be. Or, maybe a projection matrix.
I haven't actually used Arnold (yet). The stuff Frank did in the Python developers guide was great, and I noticed that he had a predefined focal length metadata key which was read by the python script.
