If you want to look at the code (the cookbook modified one), I pasted at http://python.pastebin.com/m209c67af The problem is that I dont know enough about pyOpenGL, probably the preparation phase before calls to compile must be done. Using grep / find in files for 'shader' over pyglet 1.1.1 I see some promising calls, like: glShaderSourceARB glCompileShaderARB ... Maybe you can look how pyglet calls the shader related code ? Its a pure python library, as you probably knows. -- claxo
