Hi Vincent, The ways to track whether a drawable or node is in the view frustum are:
1) Attach a cull callback, if it get's called during the cull traversal then it hasn't been culled (yet). 2) Traverse the rendering back data structures (RenderStage etc) after the cull traversal so see what drawables. 3) Test the object in question directly against the view frustum.
