I have been searching the web forever and I can't seem to find a good tutorial on how to mix a 3D animation - made in Maya - with a 2D film scene - for instance putting a CG character in a scene. Can anyone help? I would prefer the scene isn't static - i.e. locked camera - I'm sure it would be easier that way, but isn't really what I'm looking for. There doesn't seem to be much help with Maya Live - which is what I assume you would use? I'm totally lost. BTW - I am using Maya Unlimited 4.5 and After Effects 6.5 Pro.

Depends what you want to do. If your camera is static your only problem will be to get the Alpha-channel into AE properly. If you have a moving camera, you will need to use Maya Live and be prepared to use a technique called "3D Camera Tracking". I warn you, it

Thanks for the response - but does anyone know of a good book or preferably a DVD tutorial or online tutorial that I can use to learn this process?

As for my project - it would just be combining a 3D character with live action footage - kind of like "Stuart Little" but not nearly that sophisticated.

Well, you could buy this book "Matchmoving: The Invisible Art of Camera Tracking" (ISBN: 0782144039). There also are some tutorials about Maya Live, which come with Maya Unlimited (F1 brings you there).

Have fun!

Thanks - the tutorial in the help file helps, but I am having a problem with my tiff sequence - Maya says something about it not have the required length field or something to that nature.

Might have to do somthing with the resolution. Maybe you are using NTSC and Maya is set to Pal or the other way round. Maya live generates a 3D enviroment from your 2D movie with the help of your marker points. If your image aspect ratio is not correct Maya Live might throw up, before it
