Thank you for the tip. That environment variable flag helped me see that OSG found the osgdb_vrml.so plugin, but then failed when loading the openvrml.so library. I added that dir to my LD_LIBRARY_PATH and all is well!
(I don't seem to have the osgdb_wrl.so plugin by the way, but it does not look like I need it).

You can enable verbose debugging messages by setting OSG_NOTIFY_LEVEL=DEBUG before running osgviewer, and that might show if something is wrong there. It will print out where it looks for the plugin, whether it finds it, and whether it loads it correctly or not. If the plugin is there, is loaded (as printed in the debug messages) but it still says that it can't find a plugin, it might mean that the plugin depends on some other dynamic library which isn't being found at runtime. This might depend on where OpenVRML is installed and whether your LD_LIBRARY_PATH includes the right directory to find its dynamic libraries (if any) - note I'm on Windows most of the time so I can't really help more than that. > I had VRML files working with OSG 2.4 a long time ago.

The Inventor plugin can also read VRML files, so if OSG was using that one to read your VRML files before, it might mean that the OpenVRML plugin never worked for you but you never knew it... :-) Hope this helps, J-S -- ______________________________________________________ Jean-Sebastien Guay [EMAIL PROTECTED] http://www.cm-labs.com/ http://whitestar02.webhop.org/ _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
