Hi James, The easiest way to do selective picking is the use a traversal mask on the intersection traversal that maps to node masks on the nodes in your scene. For instance is you set a node mask of 0x1 on the parts of the scene you won't to pick, and 0x2 on the parts your don't want to, then use a traversal mask of 0x1 then only the parts you won't will be picked.
