- SceneExporter collects a list of child-objects for armature-object and passes it onto ArmatureExporter - SceneExporter's writeNodes is then called from ArmatureExporter for matching child-objects for bone. - ArmatureExporter removes written child-objects from list, objects not exported as being bone parented are exported as direct children of the armature-node. - Should play nice with current Second Life-compatibility. A nicer implementation would require some design changes, will have to wait.
