this is the OpenGL error (framebuffer status): GL_FRAMEBUFFER_INCOMPLETE_DIMENSIONS_EXT. The spec for GL_EXT_framebuffer_object (which is the extension used by the FBOViewport) requires all render buffers to have the same size. Do you ever attach textures/images to an FBOViewport that are smaller than ones used in a previous pass? Does your ping-pong algorithm require any of the intermediate images? If not you can ping-pong between the same images and restrict rendering to a part of the image with the FBOViewports left, right, top, bottom settings - i.e. make use of the fact that it is a Viewport ;) > WARNING: > (f:\devel\opensg\source\system\state\osgtexturechunk.cpp,1788): > TextureChunk::activate precheck failed: (null) (0x506) > WARNING: > (f:\devel\opensg\source\system\state\osgtexturechunk.cpp,2411): > TextureChunk::deactivate precheck failed: (null) (0x506) My guess would be that both of these are fallout from the FBO error there are one or more OpenGL errors queued and the precheck for activating the Textures just is the first place they are being caught.
