Paul, Sure enough, removing the PolygonOffset attribute and Polygon Offset Fill mode permitted me to write a valid OpenFlight file. Thank you for providing me with enough information to succeed at this task!!! I've caught up on some serious lost sleep! Just so you are aware, I think there are problems with not just the Subfaces, but with external references also. I'm not sure, but I thought I witnessed the FLT writer automatically making external references if a subtree of what it's writing was read in from a FLT. I succeeded only after converting all of my internal models to .osg format, then writing the master file in FLT format. Hope that is useful to you! Your pal, John Argentieri

Paul, I tried to do setAttribute( m_pPolygonOffset, osg::StateAttribute::OFF ); but I suppose your code may still be able to detect that the attribute is present. I forgot there was a removeAttribute. Do you think it's worth a shot for me to code it up and try again? Thanks!

John -- Use of polygon offset controls whether the exporter uses subfaces or not. It might be the case that the subface code has some kind of problem with texture mapping. One thing you can try is to go into expGeometryRecords.cpp and disable use of subfaces by commenting out the SubfaceHelper instances at lines 934 and 1023. This will cause incorrect rendering of coplanar polygons, of course, but if it changes the behavior of your texture mapping issue, then this is a good indication of where the problem lies. Let me know how it goes. -Paul ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Argentieri, John-P63223 Sent: Tuesday, November 11, 2008 11:35 AM To: [EMAIL PROTECTED] Subject: Re: [osg-users] BUG FOUND: FLT Writer Duplicate Node Names? 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?
