Slot for post process on model

Hello!
Sorry for my English...
I need to use shader forge for post processing.

I do the shader, wich work with a texture.

Now I need:

The texture must be my screen.
Everything what I do with texture in shader forge - must apply on my screen.
Look, how it work on this video:

So, I need the script something like on this video, but:

applying on some object, not on whole screen. On object, which has just rendered.

 

You might get the effect you want with this component I made a while ago: https://forum.unity.com/threads/applying-image-effects-to-specific-objects.473226/#post-3156198
Though this might be too performance heavy for the thing you are trying to achieve. If you e.g. just try to tint the object's color, you can just use a shader that applies a tint color on that object.

 

But your component applying on the camera. So, I cannot get 2 different post effects for 2 different objects, right?
