Hi Mark, The easist way would be to just on the culling (Node::setCullingActive(false)) for that toplevel node (with the external references) so all its children are alway traversed. Alternatively you could compute the bounding sphere yourself by using a custom Node::ComputeBoundingSphereCallback.

Hi, I'm trying to work out the best way to get a correct bounding box for a complex model (terrain actually), not one based on a bounding sphere. My model (openFlight) contains external references to other files and multiple references to the same external files with transformation matrices. I have tried walking the scenegraph nodes until I find a geode and then I expand my bounding box with the results from the geode's bounding box. I am not getting the results I would expect. Do I need to maintain the transform matrices and apply them to the geode's bounding box before I expand my resultant bounding box? Or is there an easier way?
