Rendering Shadows of Hidden Objects onto Visible Objects

Basically here is what I’m trying to achieve:
I’d like to get a rendered elevation view of a particular wall WITH the shadows of the object next to it (behind the camera). I only want to see the shadows the object is casting, so I can get an outline in parallel elevation view of the shadow cast on a neighbouring wall.

I’ve tried to use a ClippingPlane but as soon as the shadow-casting object disappears from view, so does the shadow it casts.

I’ve also tried OrientCameraToSrf but the shaows are not coming up properly

Any advice from someone who has had this issue would be greatly appreciated.

Cheers, Max.

Hi Max - I am not sure I follow, yet - is the shadow casting object visible

or behind the camera?
