Hi Chris, My plan is still to tackle the shader composition prior to 3.0. I haven't had a chance to make any more progress on it this yet as I've been hunkered down with merging submissions/bug fixes/refactors of problematic parts of the OSG. To tackle shader composition I really need to hide

Robert, Chris, et al, I highly suggest you do some benchmarking on shader compiling/link times. We investigated this a couple of years ago, and found that we couldn't avoid an output glitch (due to compile/link time) whenever we needed a new shader. GL Drivers may well have improved since

Hello, David. If your terrain is static, I would recommend an osg::NodeVisitor used on your terrain in combination with osgUtil::TransformAttributeFunctor used on the drawables of your terrain. As far as I know, this is a custom solution, so you'll have to look into both of these classes to see

Hi, you can either attach your own stencil buffer to the camera attachments, or some value osg::Camera::IMPLICIT_STENCIL_BUFFER_ATTACHMENT must be set. Have a look at src/osgUtil/RenderStage.cpp and search for stencilAttached. HTH jp sumit wrote: I am trying to do render in frame buffer
