[osg-users] Anistropy Question

[paul1492 at yahoo.com]

How do I set the Anistropy for all textures which are read in (using an OpenFlight file) to a particular value?? 
I prefer to do this without using a NodeVisitor and I do not want to effect textures I manual create and attach to the Scene Graph.
In addition, for a TerraPage file, I assume I can set the Anistropy using the:
    osgDB::DatabasePager *dp = osgDB::Registry::instance()->getDatabasePager();
   dp->setMaxAnistropyPolicy(true,value);
Correct?
