This is because the flight file supports billboarding and the flight loader
builds billboards into a performer scene graph when it sees this.

Use a format and loader which _both_ support this.

Looks like you new the answer to the previous question all along :)
I don't know what the A|W loader supports.

Yep.

IMHO use a format & loader which supports what you want.
Another popular trick is 'database overloading' :).
By this I mean you use a comment field, name or other model
property which will end up in the performer scene graph or
be passed through a loader callback and use this to identify
the element you want to billboard, environment map change
transparency of or whatever and then modify your application to
intercept/find this in the scene graph and make the change you want.
WARNING, misused it can lead to horrible situations like infantrymen
called "TREE" in your database.
