Shadow Catchers

Does anyone know how to set up a Shadow Catcher when placing a 3D object in a scene in Fusion? Are there any video tutorials for this technique?

Thanks in advance.

Render with shadows, render without shadows, pull a difference -> shadows!

Thanks, Pieter.

So, how would you combine the renders to then pull the difference?

Boolean difference comes to mind...

Thanks. I'm coming over from Nuke. I'm learning the Fusion workflow for effects.

Other method is to put a "replace material" before a second renderer and set a complete white material
Then you should have a inverted shadow catcher
