Maybe writing the field as an int instead of uint is the right
solution? I'm open to suggestions. Gordon, can you check the spec for
us on this? I'm on vacation and don't have ready access...

Hi Paul
Might well be a bug in the spec as uint is could clearly wrong in many
cases, if you bring Creator up, you will see Creator uses a -1 in many
places to mean default/not set, Such as textures, alternative color,
materials etc...

OpenFlightplugin
If I recall correctly, the flt spec states this is an unsigned
field, but
calls for -1 as a valid value. Clearly a bug in the spec.

Hi Mario, Paul and Brede,
I've done a quick review and it the change looks reasonable, but...
I'm not familiar with the OpenFlight specs.
The change is from :
_records->writeUInt32( -1 ); // Back color for bidirectional
To:
_records->writeUInt32( UINT_MAX ); // Back color for
bidirectional
So Brede & Paul, what are you thoughts? Clearly passing -1 to a
Unit32 is wrong, but what is the official spec for this?
Robert.
