Creating a playable area in space with invisible walls?

Hi, I am wondering what the best way is to create a playable area for a zero G space environment. Ideally I’d like to use one blocking cube volume that the player is allowed to float around in. However this doesn’t seem that easy as I’d need to align 6 different blocking volumes and match their corners to make an invisible cube all around the player.

Is there not a way to just make one large invisible volume that the player can sit in that will block on all the faces?

Any help on this would be much appreciated!

Ah, I think I found what I need, you can use a single blocking box or cube volume, you just need to check on the Hollow property so actors can walk around inside of it. Not sure what the difference between the cube and box volumes are…

You can just use blocking volumes, this is what they’re for. And you can still see outside:

That only works if you enable Hollow mode, otherwise you’ll be stuck inside of it.
