Hi, This is my first post to OSG. I'd like to thank all those that have contributed - I'm liking what I'm seeing :-)
I'm doing some stenciling based on the examples (using svn trunk, with ViewerCocoa (so, OSX)), but seeing strange results (what looks like a garbled stencil buffer). Upon further examination (stopping on glClear in the OpenGL profiler) the stencil buffer isn't being included in the clear. It seems the GL_STENCIL_BUFFER_BIT isn't making it's way to the RenderStage. I've confirmed it's setup on the camera. I've confirmed that there's a stencil buffer included in the pixelFormat attributes when the context is created. Just doesn't seem to be making it to the RenderStage. Unfortunately I've not managed to get the xcode debugger to play nice yet - and so I've not been able to step through to see how the clearMask is *supposed* to be set on the RenderStage. Is there something obvious I'm missing? The RenderStage clearMask is set to COLOR | DEPTH. The camera is setup like so (directly after prepareOpenGL in the viewer): Code: osg::Camera *camera = osgViewer->getCamera(); camera->setClearStencil(0); camera->setClearColor(osg::Vec4(1.0, 0, 0, 1.0)); camera->setClearMask(GL_COLOR_BUFFER_BIT | GL_STENCIL_BUFFER_BIT); And my root group node in the scene is setup thus: Code: osg::ref_ptr<osg::Group> root = new osg::Group(); root->getOrCreateStateSet()->setMode(GL_BLEND, osg::StateAttribute::OFF); root->getOrCreateStateSet()->setMode(GL_DEPTH_TEST, osg::StateAttribute::OFF); Any ideas?
