Does anyone know how to:

• have the ground material option set to "Shadow_catch_only"
• add an AO node to that material
• have the AO show up in the render?

...I normally/often just want to render without any background, but still get ground shadows so I can alpha-blend in a background in post.  But so far, I haven't found a way to get AO on the ground, without rendering some ground as well (which I don't want, because then the alpha-masking doesn't work).

Thanks,

Keith
