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
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.

[osg-users] Ambient Issues
Hi, I work in a research lab that uses a CAVE. We were recently given a large 3D model made in Google SketchUp to work with by a client. Unfortunately, we keep having issues when running it in the CAVE on OSG. The model seems to have it's ambient light amped up as it keeps glowing white and yet sometimes, if the camera is far enough, this light will fade (leading me to believe this might be a light attached to the camera. I'm not sure what it is, but the effect seems similar to when you ramp up the ambient light attribute of a model. I know not everyone works with CAVEs but does anyone think they know what the issue is? ... Thank you!
