Hi Jason, Robert's suggestion is usually the most efficient and what I use in most cases. However, if the object itself needs depth testing enabled to render properly, then another technique is to use an osg::Camera node. Set its render order to POST_RENDER and its clear mask to GL_DEPTH_BUFFER_BIT. The subgraph below the camera node will now be rendered over the main scene, but with depth testing enabled.
