I want to add objects to a scene that will have the bloom effect without everything having the effect. I've created a new node and setup the light state and so forth, but it does not seem to render the objects properly. I found it interesting that if you replace rootNode in TestBloom with a new node of your own the test gives some very odd results. There seems to be something special about rootNode that I can't quite figure out. I've gone all the way up the hierarchy and tried to see what is so special about rootNode, but just can't see it.
Try this example to see what I mean. Zoom out and you can see the outlines of the objects. Very odd.
