Dude i dont think you know what shadow catcher is. the idea of this shader which is available in basically every 3D software ever existed that is allowing to have the shadow rendered without seeing the surface this shadow is casted on. for example, a sphere placed on a ground, if this material assigned to the ground, you will see the shadow of that sphere casted on invisible ground, you will only see the sphere and the shadow with invisible ground. THAT is what we need. if someone knows how to do that it would be great to share, people keep referring to composure but that is not what it is. we need to be able to render the object with its shadow without having to see the surface this shadow casted on.
