Hi Robert, in my application I have the scene graph in some variable, and a camera in another variable, then I attach it to viewer, in multi-document window. After I close the window, the scene graph & the camera are still alive. The next time I want to attach them to a new window I get OpenGL error that the frame buffer object is not complete (and nothing is drawn), so I wanted to force the renderstage to re-create it, and achieved this by setting the rendering cache of the existing camera to NULL.
I just wanted to know if there is another and better way to deal with this problem, and also if you know why the FBO was defected after the window was closed. thanks, Guy. ----- Original Message ----- From: "Robert Osfield" <[EMAIL PROTECTED]> To: "OpenSceneGraph Users" <[email protected]> Sent: Monday, September 24, 2007 3:04 PM Subject: Re: [osg-users] FBO > Hi Guy, > > Have a look at the osgprerender example.
