It has no texture, juste one color... Thanks, Regards, Vincent. 2008/7/11 Vincent Bourdier <[EMAIL PROTECTED]>: Hi All, Just a simple question on how to set a transparency effect on a drawable. My geode contains 2 drawables, and I need only one to be transparent... I've tried : double opacity = 0.1; osg::StateSet* state = mygometry->getOrCreateStateSet(); state->setMode(GL_BLEND,osg::StateAttribute::ON|osg::StateAttribute::OVERRID E); osg::Material* mat = (osg::Material*)state->getAttribute(osg::StateAttribute::MATERIAL); if(!mat) { mat = new osg::Material; mat->setAlpha(osg::Material::FRONT_AND_BACK, opacity); state->setAttributeAndModes(mat,osg::StateAttribute::ON); } Lightning is already set to ON... But nothing appear transparent... Thanks, Regards Vincent.
