Hi Akilan,
statSet->setMode(GL_LIGHTING, osg::stateAttribute::OFF);
[...]
osg::ref_ptr<osg::Material> material=new osg::Material; material->setAlpha(osg::Material::face::FRONT_AND_BACK,0.5); statSet->setAttribute(material.get());
As Paul mentioned in a previous message in this thread, you need lighting ENABLED to be able to use materials. Otherwise the material has no effect.
Note that setAlpha might not do what you want - it sets the alpha of ambient, diffuse, specular and emission colors. I think you'd probably just want to set the alpha of the diffuse color, something like
osg::Vec4 diffuse = material->getDiffuse(osg::Material::FRONT_AND_BACK); diffuse.a() = 0.5; material->setDiffuse(osg::Material::FRONT_AND_BACK, diffuse); Hope this helps, J-S -- ______________________________________________________ Jean-Sebastien Guay [email protected] http://www.cm-labs.com/ http://whitestar02.webhop.org/ _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
