Hi, I have many osgText::text objects flying around a 3D scene (ie, not in a HUD) and transparency is not working correctly. The quads of the text in front entirely occlude the text behind, even though transparency is enabled.
Other geometry shows up fine. See the attached image. The white text behind is occluded but the lines of my grid are properly drawn through the transparent regions of the letters. [Image: http://forum.openscenegraph.org/files/spinviewerscreensnapz003_175.png ] If I move the white text in front, both are drawn perfectly. ie, it seems to have something to do with their order of creation (or traversal). For both, I enable blending, depth test, and provide the TRANSPARENT_BIN rendering hint: Code: labelStateSet->setMode( GL_BLEND, osg::StateAttribute::ON ); labelStateSet->setMode( GL_DEPTH_TEST, osg::StateAttribute::ON ); labelStateSet->setRenderingHint(osg::StateSet::TRANSPARENT_BIN); I have played with manually setting rendering bins, which can force a particular text to draw in front of another, but I want all these pieces of text to automatically sort and render correctly without manual input. Any hints?
