Hello, I've added possiblity of setting FOG shader flag at CoreModel load phase. Try CoreModel::load( cfgFileName, osgCal::CoreModel::FOG_EXP ) to get models with fog supported. Besides FOG_EXP you can use FOG_EXP2 or FOG_LINEAR flags. Currently it's not possible to enable/disable fog dynamically for Model, only for CoreModel at load time. Fog parameters are set using osg::Fog state attribute. Hope it helps. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
