Hi, I'm trying to do motion blur just using OSG rather than osgPPU and I had intended to use the fragment shader from osgPPU which uses two textures holding the current and previous frames and mixes them together to produce the desired effect. All I need to do is store the current frame as the last frame after viewer.frame(). Or so I thought.
My initial idea was just to write the current frame's texture image into the last frame's texture image, but this does nothing - the last frame's texture as displayed post-shader never changes. Is it a callback I need? If so what? Any help greatly appreciated.
