Okay, I come calling out for help from those of you whose brains swell unbearably with knowledge!

I need help with the Maya API, specifically integrating an MFC program into it.

I need to have some custom nodes that have their own attribute editor bits, then I need to open a window that displays my own OpenGL rendering of the current scene. I need to be able to access polygonal mesh data for the scene and finally I need to hit a render callback, not only when you click the render button, but also for each frame of a batch render.

Phew! That's quite a lot! The most difficult and important part I think will be the window with the OpenGL rendering (I really can't do this is a viewport), it's essentially to allow me to edit my custom drawing stuff, so I can't really do it in a normal viewport

If anyone has any experience of any of these bits, or knows anyone who does, can you please, please get in touch with me!

Thanks!
