How can I create a material with a border and a transparent body

I want a material that has 0% fill opacity with a border, like this: Screenshot - c96818c8a3226a6ec1f6f94fd7103cef - Gyazo

I tried googling this, but all I could find were posts on postprocessing, which isn’t what I’m looking for.

This is probably super simple. I just don’t know the terms UE4 uses to define these things.

make a black/white image where white is what needs to be shown, black what needs to be invissi.
set the material to masked, plug this “mask” texture into it and done :slight_smile:
