Hi Robert, If you want to just intersect certain parts of the scene graph you can use a combination of NodeMask on the nodes and TraversalMask on the NodeVisitor/IntersectionVisitor, the two masks and logically "AND"'d to decide on whether to traverse a subgraph or not.
Alternatively you just start your traversal at the Terrain/TerrainTile nodes themselves. Robert.
