Hi there guys.

I've been tinkering a bit trying to achieve a proper matte shadow "state" for objects in the scene so I can render just an object inside the scene maintaining the light around it but getting just the object and the object casted shadows and GI.

So far I tried to di this:

And I get this, wich is a cool beauty, and an uncool alpha.

Now I'm wondering how to avoid all this lighting effect in the environment because I need the object and it's effect in the rest of the scene (in this case the text) and I need the reflections and the light to be the same as in the actual real scene without shadow catcher, so I need all the objects with the correct material for GI/Reflection/Refraction,and I override this material just for direct.

if I use the shadow catcher in the Global Illumination slot, as you can imagine all the reflections and lighting change, but I get the alpha I need.

So the question is how can I achieve the beauty of the first sample and the alpha of the second sample in the same render?

Best regards!

P.S.: I forgot how to include attachements in line, can someone refresh me this so I can include the pictures in the post?

Hey guys, no ideas here?

Dev team? (Maybe it's a more appropriated question for you than for artists)

Cheers.
