Re: [osg-users] Ambient Issues
Hi Jordan, Have you tried running your model through osgconv to convert it to an .osg file? You should then be able to look at the structure of the model in a text editor and rule out any issues with it. osgwnames from osgWorks is also a great diagnostic tool for models. Hope that helps.

Try something like this: osg::StateSet *ss = model-getOrCreateStateSet(); ss-setMode(GL_NORMALIZE, osg::StateAttribute::ON); --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
