Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Hi,
This .blend file will demonstrate two shadow catchers overlapping each other and creating double shadows. It would perhaps be interesting to add a termination value for the amount of shadows cast or just removed entirely.
Thanks!

Hi Bastien, something went wrong, could you make this valid again?
Added subscriber: @Sergey
@Sergey iirc that was your work?
Added subscriber: @esminis
I don`t think this is a bug as shadow catcher does not block shadow, if you add 10 stacked shadow catchers they all will catch same shadow.

Can confirm the behavior
This might very well not be a bug, but a limitation instead.
However, I would also expect (in an ideal world) to somehow not have the shadow catcher pick up a shadow if it has already been picked up by another.
Havent done any research on how to achieve this, just saying...
Maybe @Sergey wants to share his wisdom?
Added subscribers: @brecht, @JacquesLucke
Maybe @brecht knows if this is a known limitation of the Cycles shadow catcher.
Just for quick reference, this is how the file looks like:
Note, the intersection of the cube with the top plane is not necessary.

I don't see the second shadow anymore in Blender 4.1.
