Other osgPlugin readers treat the node names as human readable ones. If someone names a node in the modeling process, there's a good chance they're going to need it at runtime. I'd argue alongside Matthias that the Name is the more important label to preserve. The ID is largely useless once everything is loaded. A possible solution would be to subclass osg::Group inside the loader and add the additional fields to it (one for ID and one for SID). The TXP loader seems to do something like this, so there's precedent. Just an idea... --"J" ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] Collada Reader - name import
Hi, i want to import a 3d model from a collada file. This works fine, but all the names of the Nodes in my scenegraph are set to some IDs like "ID1057". So i looked to the .dae file and found something like this: obviously the osg collada importer sets the name of the osg::Nodes to the IDs from the collada file but i would expect the osg::Node's name to be "Line01". here is the code from daeReader.cpp: Line 546: resultNode->setName( node->getId() ? node->getId() : "" ); shouldn't it be: resultNode->setName(node->getName() ? node->getName() : "")? or is there a special reason to use getId() instead of getName() here?
