Rendering shadows on transparent background / converting model from cycles to internal render I'm trying to render a model over existing video footage. So I need to render the shadows on a transparent background so it can be superimposed on the footage. I know there is a way to do this in the blender render and not cycles but I'm getting stuck with this file. I can't get the model of the building to show up in the render, I think it has something to do with me converting this from cycles. And I can't get any shadows to be cast at all. I've attached a link to the .blend any help would be greatly appreciated, thanks.
