This usually happens because of overlay planes. The trick to get the
"transparent" color index for the overlay planes varies from system
to system. If Inventor doesn't get the right index then the overlay
planes may be cleared to opaque black. The simplest solution is to
tell Inventor not to even try to use overlay planes. In the TGS
version you can simply set the environment variable OIV_NO_OVERLAYS,
but I don't think that's in the SGI Open Inventor.
