I followed the tutorial exactly. I applied it to my model and my plane, which already had a 'use background' shader applied to it, since I want to combine it with video footage. After I followed the steps, this is what I got:
Not what I wanted. The AO is fine but I'd rather see no trace of the ground-plane. I've tried everything but I can't get it to look decent. Does anyone know how to fix this? In case it makes a difference: I use Maya 2010 64bit instead of Maya 2009 for which the tutorial was made.
Thanks for replying, I didn't expect to get a reply anymore.
I found out what the problem was: it turns out Maya can't properly blend the layers (or at least can't handle the multiply blending mode). Photoshop/AE can. So creating some separate render passes fixed it, as long as you composite in PS/AE.
Now I only got to fix my tracking, but that's a whole different story.
