Hi Christopher, I think the problem is that fusion distance is not being calculated.
Most of the manipulators calculate fusion distance using an intersection test or distance to the center of the bounding sphere of the specified node. Probably the camera manipulator to handle animations is not updating the fusiondistance so the eye separation is incorrect. A workaround could be set an EventCallback inside the root node and inside the FRAME event calculate properly the fusion distance. In an EventCallback you have the node, the Viewer and probalby all you need to compute it correctly. You can approach the fusion distance using simply a distance to the center of the bounding sphere of the node or if you want a more accurate eye separation (for example for terrains) you can calculate a test intersection. Hope this helps, Rafa.
