Hi Vinay, I don't if it's a typo, of the code you are trying to use is exactly as you've set it, but you inhertiedWindwData is most definately wrong, it should something like: traits-inheritedWindowData = new osgViewer::GraphicsWindowX11::WindowData(m_hWnd); Note the inclusion of WindowData.

Hi Maxim , I believe the readPixels is reading from the framebuffer and not the texture (or am I mistaken??) remember a RTT usually means I have 2 or more cameras in my scene... where one is used to do the RTT... so this can lead to a question how would osg::Image know which buffer to read from?
