I've spent quite a while looking at the scenery code to see where the bv-trees are being generated and saved to the SGSceneUserData, but so far the only place I've found that calls the BoundingVolumeBuildVisitor is the groundcache and ModelRegistry. Furthermore, calling getBVHNode() on the SGSceneUserData associated with a tile nevery returns anything. Am I just missing something completely here, or is there coding required to generate the BVH trees for the scenery tiles themselves (presumably based on the groundcache code?) -Stuart ------------------------------------------------------------------------------ BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA The must-attend event for mobile developers.
