reflection on a plane

[celmar]

hello!! i have a scene with, let's say a cube on a shot... the shot is textured, and adding some reflection would "damage" the texture... but is there a way to use a p)lan, above the textured shot, like a shadow catcher, which would capture just a reflection of the cube... i tried with a shadow catcher material, but the shot is all black except for the reflected cube... thanks for your suggestions!
