Hi, Have your textures got an alpha channel? Try setting the alpha of the black region to zero and set an alpha function of GEQUAL and a reference value of 0.05
So, declare a member variable: Code: osg::ref_ptr< osg::AlphaFunc > m_refAlpha; Then: Code: m_refAlpha = new osg::AlphaFunc(); m_refAlpha->setFunction( osg::AlphaFunc::GEQUAL, 0.05f ); m_refStateSet->setAttributeAndModes( m_refAlpha.get(), osg::StateAttribute::ON ); The billboard tutorial shows this.
