[osg-users] Large number of occluder nodes

I have a scene with a large number of occluder nodes. Its a large city scene, and most of the nodes are relatively small, like 10-50 meters wide, like 10-30 meters tall, in a database that is maybe 20 km x 20 km. I have 1000's of these. They are basically extracted semi-automatically. Most of them are simple just a 4 points. 

My cull time is getting up to the 40ms range. They really help in some regions, but I really don't think I need them being considered during the culling stage for anything node that is more than about 5000 meters out.

What is the best way of managing occluder node lode?
