Hi Fred, The osg::Camera has support for setting the reference frame so that it inherits the viewpoint for LOD calculation so that you get the same LOD's for your render to texture pass as you would for your main view. In osgShadow you'll this used and set up thus:
_camera->setReferenceFrame(osg::Camera::ABSOLUTE_RF_INHERIT_VIEWPOINT); This doesn't require any other changes so no need to try Sergey's suggestion of LODScale() which would achieve rather different results.
