From Glenn Waldron, "Attached is a patch for osgUtil::Optimizer. If you run the SpatializeGroupsVisitor on a scene graph containing Geodes, StateSets attached to Geodes can be lost.

Browse Source 
The problem is in SpatializeGroupsVisitor::divide(osg::Geode*, unsigned int) where the code creates a new Group and divides up the input Geode into one Geode per Drawable.

I fixed the problem by assigning the Geode's stateset to the new parent group.

To replicate the bug, see attached osg/dds files:

osgviewer b.osg -- model renders correctly
set OSG_OPTIMIZER="SPATIALIZE_GROUPS"
osgviewer b.osg -- textures are missing."
