Hi,
The change in this submission is for Texture Attribute File as described from
version 16.1 of OpenFlight documentation.
In fact, I believe that it is only the documentation that has been corrected,
the file format was even before that the same.
The attached file is based on OpenSceneGraph 2.3.4.
Regards,
Lars Nilsson
