HI again,

I've got a shot where i'm rendereing out a chan element with bullet. it crashes down on a plane. I'm just rendering the element.
but i need a shadow pass -

I've got it currrently with a white bg floor and the plan is to render the same pass out with objects excluded or turned off so that just the shadow shows.
the shadow will be on white, and i dont think i get an alpha of the shadow.

anyone know how to isolate a shadow pass better than this?

I didn't see a shadow buffer - i wonder if this is a buffer newtek could add in the future - sure would be useful just to have a shadow buffer pass.

does exr save out a shadow buffer pass - or the photoshop export?
