clipping plane effect on every material

Hello, there is something I don’t find anywhere on the doc : how to create an effect that will apply to every material ?

I’m trying to create a stargate (like the movie) and I can’t find how to apply the clipping plane effect (for disintegrate partially the body) on every object that is trying to get in the portail, how to do it when you have hundred of different material that isn’t supposed to do that effect ?
what I mean is that I want every object that can move in the game to start begin disappear when they move through the stargate.
I can’t change all the material, so any idea please ?

Thanks you !
