Change opacity of Text Render

I need to be able to change the opacity of the text render on my actor.

I cannot find the translucent or opaque materials used for the fonts, as they say to be under Engine/EngineMaterials but that folder does not exist in my directories.

I don’t see much of another way around this.

There is a button In lower right corner of content browser “view options” - click it and check ShowEngineContent

Found the translucent text material. Using that, it’s still not changing opacity. I am changing it via the color, but I don’t see an option to change the opacity anywhere else.

Is there any solution by now?
