How to make the reflection appear only on mesh renderers from one layer or on one mesh renderer only?

Hello.

I’m making a racing game and want to make a reflection probe for the car only. After making I’ve noticed it’s also reflecting on other objects. Making it tighter doesn’t help and also (for some reason) starts to not fully reflect on car when moving. So, here’s the answer: how to make the reflection appear only on objects from one layer? Also, I’m using deferred rendering.

BTW here’s the pic of the problem. I expect only the one car to use the probe (I’ve made it brighter so the bounds can be seen). In reality I have all the objects in bounds using it.


EDIT: It’s not answered in two weeks! Maybe someone will pay attention?

So basically the only solution to fix this using deferred rendering is to write a shader. It’s too complicated for me, so I just decided to switch to forward rendering.
