Im trying to create a dream material with nodes that can be used as backdrop for 3D elements.
The material needs to be invisitble in general but still recieve shadows BUT it also needs to cast shadows on everything else than itself…
Do anybody have any ideas if this is possible?
BTW. This is not the usual “shadow only” compositor trick.
I am looking for a node based or OSL based solution.
I want this solution too. The Ray Visibility trick isn’t working for me. I wish it were that easy. It just doesn’t react to anything when I turn off Camera rays. Can you provide an example blend? Cheers.
