How do I get these weird Material Emancipation Grills? [closed]

I was playing a community-made Portal 2 and i came across weird looking Material Emancipation Grills. There were a couple of them, a purple one and an orange one, and they both did something unique. For instance, I remember the orange one wasn't able to be passed through by anything, but you could shoot portals through it.

Bellow is an image from the internet i found of what i am talking about as I can't get a picture of them, whenever I try to the game crashes.

I was wondering how to get this "Mod", or just any way to get these items.

To create maps that use these, you'll need to be using the Portal 2 Authoring Tools rather than the in-game Puzzle Creator.

Emancipation Grills consist of at least two objects. One controls what it looks like (prop_dynamic) and the other controls what it does (trigger_portal_cleanser). The latter can be configured as to whether allow Physics Objects (like cubes or turrets) or not.

To block objects and allow portals likely requires tweaking different settings so that it acts like a window rather than an emancipation grill.
