Hi Olaf, maybe I can tell you from a screenshot. From memory, we need at least GL_ARB_framebuffer_object and float_texture
I don't know what extension or declaration is required to have "unsigned int" uniforms (osg_FrameNumber in src/Main/CameraGroup.cxx) Regards, -Fred ----- Mail original ----- > De: Olaf Flebbe > > Hi Fred, > > I did see a composited view in the window (with different views at > the edges of the window).
