Since there has recently been a chorus of complaints about the flight
loader previously, I'll add my voice. We've had several problems for
many years now, and if there are going to be problems fixed in the
loader, we'd like to see the following problems addressed:
The transparency property on OpenFlight faces and objects doesn't work.
The object or face is rendered fully opaque, unless there is a
transparent material applied. (since Performer 3.0):

Loader options, such as PFFLT_FLATTEN and PFFLT_CLEAN don't work (since
Performer 2.4):
http://oss.sgi.com/projects/performer/mail/info-performer/perf-01-11/0029.html
Also, I don't know if this was ever fixed, but at one time, nodes with a
name that is 8 characters in length are not loaded properly (also since
Performer 2.4):
