I'm converting an old project from Max 5 to Max 6, and one of the things I'm struggling with is how to recreate the OpenGL preview features I used in that project. I used to use @shared_context and @copy_texture to copy the full OpenGL buffer from one context to another for a preview window: this worked fine in Max 5, but doesn't in Max 6. I'm aware of the new 'shared' attribute of OpenGL contexts, and have substituted these for the old '@shared_context' method, but can't get the following to work. Could anybody shed some light on this please?
I'm running Max 6.1.2 on a Macbook Pro Retina 15", OS Mountain Lion.
