Hello, unfortunately this does not work for me. Maybe I have to do something special in the FirstPass_ or setup the camera in a special way -- I don't know.
Can someone clarify is here something special missed or what is right way to exchange the FBO render target the light-way (without triggering heavy setCameraRequiresSetup()) ? I do it exactly the same way: Code: if (cam && cv) { mImage= mRttTarget->getImage(osg::Texture::FRONTFACE); if (mImage) { if (mInitialFrame) { mInitialFrame= false; cam->attach( osg::Camera::COLOR_BUFFER, mImage); } else { #if 0 cam->attach(osg::Camera::COLOR_BUFFER, mImage); // heavy way, TODO: light-weight FBO render target exchange possible? cv->getCurrentRenderBin()->getStage()->setCameraRequiresSetUp( true); #else // cheap fbo-target exchange will not work. osg::FrameBufferObject* fbo = cv->getCurrentRenderBin()->getStage()->getFrameBufferObject(); if (fbo) { fbo->setAttachment(osg::Camera::BufferComponent(osg::Camera::COLOR_BUFFER), osg::FrameBufferAttachment(static_cast<osg::Texture2D*>(mRttTarget))); } #endif } } } Cheers, Alexej J.P.
