Question How can i isolate the render texture from the global custom post processing shader (Blit)

I used this method to create custom post processing effects using render feature. The problem is whenever i apply the effect, It applies globaly on the screen (Scene Window, Main Camera, RenderTextures), The render texture that i'm using renders only one layer but still it has the effect on it which ruins the whole thing. The effect is kinda "baked" to the scene.

 

I fixed the issue by adding a renderer to the renderer list, then assign one per camera. That way, i can apply the effect exclusively to the renderer.
