If a ray is being traced not from the camera but as a recursively reflected/refracted ray, would a BVH tree still force this ray to start its search from the top of the hierarchy, even if it originates from within the hierarchy instead of outside it (as would be the case for camera rays)? This seems kind of inefficient and I was wondering if there would be ways to determine a more optimal starting point in the hierarchy for this type of ray.
