How to set Corona Shadow Catcher "invisible"

[Ennex]

Hey guys

how can I set the Shadow Catcher Plane "invisible"? In my rendering I just see the reflection of the Shadow Catcher not the plane itself but if I save the image as PNG for post production I also do have the plane in my image.

Thank you very much!

If you don't need shadows from the buildings, but only reflections on them, then the easiest option is to change shadowcatcher's alpha mode from always solid to always transparent. If you need shadows as well, then you need to use third option - for compositing.
