Perhaps you can email a small file the exhibits the problem? I'd like to
examine it ans see exactly what's happening.

Is there any common content to the problem files? like BSP's? or instancing? or
rgbmode colors? etc.

Evans & Sutherland oem's MultiGen v1.1 for NT and also extends the OpenFlight
V15.1 format to directly support some features of their Image Generators. The
loader doesn't understand any such extension records.

Endian refers to the ordering of bytes in a word that a cpu reads and writes.
Intel based computers are little endian, while SGI computers are big endian.
The loader can only read big endian files. The reason why I said this was
remotely possible is because pre-release GameGen v1.0 for NT wrote little
endian OpenFlight files. Since OpenFlight files are always big endian by
definition, this was corrected in the release version.

Regards.
