Yes, I also think so. And it's strange to me, why this feature exists if its buggy. Of course I can draw shadow manually in Photoshop, but it will take more time and it won't be as realistic as Octane makes it so.
I find DayLight for me the most preferred light, maybe it's the reason of such shadows ...

Polygons really were inverted, but still nothing has changed

Greetings. I have 2 issues connected with shadow catcher.

1. Why do I get strange shadow like this?

1st image - flat render with background. Normal shadow.

2nd image - alpha render added on a solid in Photoshop. Shadow is awful.

2. Why I can't apply ...
