[osg-users] Transparency on a drawable

[Vincent Bourdier]

Hi Stephan

Yes GL_BLEND is on :

osg::StateSet* state = g->getOrCreateStateSet();
>
> state->setMode(GL_BLEND,osg::StateAttribute::ON|osg::StateAttribute::OVERRIDE);
>     osg::Material* mat =
> (osg::Material*)state->getAttribute(osg::StateAttribute::MATERIAL);
>     if(!mat) {
>         mat = new osg::Material;
>     }
>     mat->setAlpha(osg::Material::FRONT_AND_BACK, alpha);
>     state->setAttributeAndModes(mat,osg::StateAttribute::ON);
>     state->setRenderingHint(osg::StateSet::TRANSPARENT_BIN);
>     state->setMode(GL_LIGHTING, osg::StateAttribute::OFF);
