[osg-users] Approaching regions with many nodes

[sam]

Hi Sebastian,

Is this approach still valid with lots of little nodes that have no LOD
detail against them? Or should I just tell my brain that the LOD part of
the node isn't really applicable for what I'm doing and continue with your
advice?

Thanks, Sam
