Hi Shayne, Is each LineSegmentIntersector instance getting more than one intersection result? Or is the total number of results among all intersectors more than 1? The limit is applied to each intersector instance, so the total number of results should max out at the number of intersectors being used.
You can try applying the limit to the IntersectorGroup object as well, but you might still get more than 1 result. However, I think the "IntersectorGroup::intersect" method can be modified to break out of the intersector iteration if the limit has been reached.
