Rendering shadows only

[cribbidaj]

Is there a way to render a model performing an action in a choreography so that the model and it's shadow are all that render with alpha channel = ON in the rendering options? Basically, I want to render a scene to targas with alpha channels with only the model and it's shadow appearing in each frame.

I think we've touched on that one before. Here's a search for "shadow" and "only"

 

Try "Shadow Pass" first.
