I must admit I'm stumped, John. From looking at the code in the exporter, I can't see how it could possibly clear the texture palette override flag when writing the external reference record. The spec says that when the flag is set, the child FLT file should use it's own palette. So this should work. I advise you to export to FLT under the debugger and step through FltExportVisitor::writeExternalReference (expPrimaryRecords.cpp line 411) and make sure that the "flags" written to the record really does contain the bit for the texture palette. -Paul

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.

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.

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.

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 _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Argentieri, John-P63223 Sent: Friday, November 07, 2008 11:42 AM To: [EMAIL PROTECTED] Subject: Re: [osg-users] FLT Writer Duplicate Node Names?

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. -Paul _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Argentieri, John-P63223 Sent: Friday, November 07, 2008 8:41 AM To: [EMAIL PROTECTED] Subject: [osg-users] FLT Writer Duplicate Node Names? 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?
