Using Shdow catcher mtl in complex interior scene

[mferster]

I honestly think it would be easier if you rendered your shadows separately from the furniture instead of spending hours and hours experimenting for a solution that likely doesn't exist at the quality you are looking for.

Plus you have more control in the long run with your layer ordering and color correcting your shadows or the furniture itself in post.

Have you tried any other options?

As I mentioned before, if it's not possible to render the shadows together with the objects - we'll render them separately, but our main concern is that the shadows without the environment map on a backplate don't look realistic - they are solid black or gray. And in my attempts I even rendered the HDRI map of the room and used it for a backplate, but I got strange light reflections around the places, where metal (or other reflective surface) touches the shadowcatcher. But this works only for static render. And we need these shadows for video production.
