Hi all, I have been encountering the same problem for a week and i still cannot solve it. Currently, I am creating a 3D model for my application. I had successfully created a 3D model, which is launch straight alway. However, this time, i am trying to have my mainViewController and link to my EAGL view. The linking works but they say create frame buffer fail 0. my main nib based file is my mainWindow, which contains my 3D model. How do i get rid of this create framebuffer fail 0? Any help is appreciated, I am really stuck..
