How can I make a character disappear from view from one side to the other?

A picture is best for this one:

It is what you think it is. Moving through a portal, which will relocate the character to a distant position.

As shown by the “Angle” picture, the camera could be looking at this from any direction.

If the portal is completely between the camera and the green ball, blocking the view, then the green ball won’t be visible but it still has to not come poking through the back of the portal (which the camera can see).

I should have looked harder on this one.

A working solution I’ve found is here:

Hide Objects with a clipping volume or plane?

I am trying to clip out an object from the Main Camera from a certain vantage point only. I have attached a project with a simple ping pong animation on the main camera. What I am trying to accomplish is simple: I wish to be able to see down...

Fancier effect that I haven’t tried is here (check out the Youtube vid too):
