Hi Ulrich
thanks for help.
I use/try this code for the moment :
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);
But nothing appear transparent...
Regards,
Vincent
