Create a "light catcher" ?

[wrapthereal66]

hey ! i'm a vfx artist hand we all know that for integration you need a plane or something with a shadow catcher !
but for light its seems more complicated
my question is : how can i reproduce this texture for catch the light of a emiting objet ?
because for exemple if my ground is a shadow catcher and i want to output a light pass or something , the ground is obviously invisible !


so yeah if someone can help me with this ! thanks you !

Hi wrapthereal66,
Using render pass layers, you should use "shadow pass" layer instead of shadow catcher and light pass ID as in screenshot.
