Hi David, I haven't looked at the code yet, do you have some example data I could look at that illustrates the bug?
I not clear on your explanation, but it sounds like the MergeGeometryVisitor isn't coping with dodgy data properly, by dodgy, I mean that having the same Geode appear multiple times in a Group is an example of broken scene graph to start with. How the scene graph got into this broken state is an entirely separate issue but needs to be tacked down as well as it suggests something else is broken in either one of the OSG loaders, one of the Optimizers, or in the original end user database. If you have a fix then please submit it, but I'd like to be able to reproduce the issue and understand it fully when reviewing changes. Cheers, Robert.
