The beauty pass, in your scene, has a black background.
I think we need to get rid of this black background.
How can I change this in octane's settings? Alpha's?
The shadows layer has a white background, same here, I don't need that. Alpha?
Reflection layer is okay I think, in Photoshop I can place them with Lineair Dodge (Add).
So almost there
Thanks so far!
