I don't think there are other textures involved to add MSAA to.. two other blur units before the UnitInResampleOut could help yes,
also notice that the radius should be about 2.5 - 3 times sigma to make sure the entire kernel is used instead of cutoff by the radius. grtz, René 2011/11/24 Jean-Sébastien Guay <jean-sebastien.g...@cm-labs.com> > Hello René, > > > maybe multisampling can reduce the problem. >> > > The screenshot was with 4x MSAA active (in the camera->attach(...) call of > the HDR code, where we bind a texture to the main scene camera which is > then passed to the first unit in the osgPPU pipeline). > > Perhaps you're suggesting I enable MSAA for one of the other stages in the > pipeline?
