How to mask an invisible object?

Hey Folks,


Let's assume we have a cube and a sphere. from the camera angle, we will see a cube behind a sphere.


I need to hide the sphere from the beauty pass but still, I need to have a mask for this sphere.


what I have tried is that, I turn the sphere visibility off. and create an Aov mask for it. but once I turned the visibility off the mask goes off too.


I also tried to make a shader for this sphere with opacity. but it ended with no Masks too.


I tried to work with ray switcher and trace sets but without any results too.


so what should I do to achieve this result ?


Thanks,

Azab

You could set the ray_switch.camera color to the same as your background.
