How to select Actors with only collision components in the Viewport

I cannot left-click on Actors with only a collision component (box, sphere, etc.). I need to be able to to place invisible walls in my scene. I don’t want to have to add a Static Mesh Component to my Invisible Wall blueprint.

I googled like crazy and couldn’t find an answer to this. It seems like such a simple issue to solve but I couldn’t find any apparent solution.

If you want to place invisible walls, what’s wrong with scaling a cube, and then marking it as ‘hidden in game’?

( I’m not quite sure I understand your problem )

Shortcut “T” allows you to select translucent actors. If that is not it, try searching the shortcut keys for “Select” it might get you what you are looking for.
