Visibility layering - hide to player but not to SceneCapture2D

Hello everyone,
I’m new, so my question may look trivial.

I have a SceneCapture2D rendering to a renderTexture. I want some text (but could be anything else) to be visible on that texture (so visible to the SceneCapture camera), but not in the game itself floating around.

It was actually rather easy to do in Unity (layers, top of the screen) but I can’t find a way to do this in Unreal Engine. The layers of Unreal don’t seem to do this by default, but I’m willing to do some blueprints (or even some code, I’m a programmer by trade).

I’m so far quite impressed by the quality of the engine and I’m surprised that something so useful doesn’t seem to be present at first glance.
