Select all meshes (or actors) (including obscured ones)? ctrl + shift + alt drag doesn't work

I have a few meshes that I need to organise and I want to do so by selecting all meshes/actors in my viewport. I’m happy to do this in perspective or orthographic view.

I tried ctrl + shift + alt + drag left mouse button but it only selects what is in view and not occluded actors.

Any advice? I can’t seem to find any information!

Hello !

Change the view mode from “Lit” to “Wireframe” so, as everything will be seen in the screen, you can select all with [Ctrl] + [Shift] + [Alt] + [Click]

I hope it helps you!
