WA for out of vision raid memebers

[Alrik99]

I need some help with some weakauras, I need to know which members of my group are out of vision, behind a column, etc.

I have seen auras which are able to mark people on the raid frames based on debuffs, auras which are able to say if you do not have any healer in range, but I have not seen any aura checking if some raid memeber are out of vision

Is it possible to do this aura?

It is not possible. The API does not have the ability to test pathing or obstructed vision. That can only be checked upon attempting to cast.
