Hi, I'm working on a feature that requires modifying a scene graph after it's been loaded, including those that may be loaded from the DatabasePager. Unfortunately the process depends on any ancestor transforms that may be present in the graph that the node may be merged into. I've looked (at some length) at both a ReadFileCallback and pseudo-loader plugin as implementation options, however neither appears to provide any way of 'seeing' whether a readNode request comes from the DatabasePager or elsewhere, and if it does, where it will end up in the rendered scene graph. Am I missing something obvious that would help in this situation? Otherwise I may look at modifying OSG to pass a reference to the parent node in the ReaderWriter Options or something similar.
You could attach the parent node address (or the full NodePath for that matter) as UserData to your ReadFileCallback instance.
