More straightforward manipulation of render pipeline

Hey! So cool that we can sort of alter the render pipeline using post effects. As of now the only way to isolate assets so that only some of them are affected by the post effect is by creating a new 2D screen image and adding a new render texture, rendering your assets camera to that render texture and displaying it that way.

This is a bit confusing and I still don’t understand how I was also rendering in the background camera texture, so a more straightforward way to isolate groups of assets for post-processing would be so cool! The way the program is set up hierarchically already lends itself to this - the way things are grouped in the scene panel.
