Paul,
 
I'm not sure what the problem is, but I can see that when I create a
scene graph with ProxyNodes in memory, and write that scene graph to an
OpenFlight file using 2.6.1, the external references are somhow broken
with respect to textures. If I convert that  to an .osg and back to .flt
using osgconv from the command line, it seems to work in the 2.6.1
reader, all the way down to OSG 1.2's primary reader when osgdb_flt.dll
was mostly phased out.
 
However, none of the OpenFlight files generated by 2.6.1 can be opened
using the FLT reader in OSG 1.0 / osgdb_flt.dll. Do you have any idea
why that is? I get a single group node, so nothing even gets drawn in
this case.
 
Thanks,
John

Thanks, John. If you fix this, please post the fix to osg-submissions.

        Paul,
         
        Attached is an example of a bug I found in the FLT writer. If
the GL_POLYGON_OFFSET remains inside of extref.osg, then converting it
to FLT using osgconv will cause the texture of the external reference to
disappear. If the GL_POLYGON_OFFSET is removed from extref.osg, then
extref.osg is converted to FLT using osgconv, the texture on the
external reference remains.
         
        Thanks,
        John Argentieri

        Guys,
         
        Has anyone used the ProxyNode in this way, in OpenFlight files?
My primary file and my externally referenced file are both OpenFlight
files. The externally referenced file gets loaded, but the texture is
incorrect. The texture applied to the model, in my case, is the only one
that is used internally in the primary OpenFlight file. For example, my
terrain surface is internal and textured as grass. My externally
reference tree models are shaped like trees, but also textured in grass.
I've tried moving the tree's texture files around to be sure that it
wasn't a path issue. It didn't work.
         
        Is there anyone that can help me to resolve the issues I am
having? All I want to do is write an OpenFlight file that contains
several clones of another OpenFlight file. The straightforward approach
breaks -- not for the current OSG loader, but for other loaders that
expect node names to be unique.
         
        Your friend,
        John Argentieri

        The exporter writes an external reference record when it
encounters a ProxyNode. The importer should do the inverse operation.
         
        I searched for the error text you mentioned, but could not find
any code in OSG that displays that error, so I can't really help you
with that.

                Paul,
                 
                Is there a way that I can place multiple instances of an
external .flt file into another .flt file? I'm trying to use ProxyNode,
but still getting these errors:
                 
                Non primary record found as child. op=19
                Non primary record found as child. op=19
                Non primary record found as child. op=20
                Non primary record found as child. op=20
                 
                Thanks,
                John

                The exporter dumps the Node name to the FLT record name,
just as the importer does the inverse operation. I don't believe there
is any code to check for and avoid duplicate node names.
                 
                I'd think it would be up to the application to specify
unique Node names, as the exporter has no other way to know what text
should be written to the FLT record name. I can see how it might be
useful to have a "I don't care what you name it, just make sure it's
unique" mode. Currently, this doesn't exist. You are welcome to add it.

                        Hello all.
                         
                        Does the FLT writer create duplicate node names
for nodes with multiple transforms as parents? We're having trouble
sharing a single model inside of multiple transforms scattered about.
Some older OpenFlight software we are interfacing to does not like this.
Any thoughts guys?
                         
                        Thank you,
