How to hide what is rendered behind a gameObject ?

[PMerlaud]

Hi,

I’m generating meshes at runtime in my app.
I have 2 meshes in my scene :

I’d like to know if it’s possible to hide anything that is renderer behind the red mesh (so it would look like there’s a whole in the blue on) ?

Here’s what I’d like to render :

Could that be achieved using a custom shader that could hide stuff behind the gameObject to which its applied ?

Thanks

This shader should work for you.
