This seems like a simple fix but I just can’t find it but I just want to make a box/square hollow to be able to put an object inside. Every tutorial or video I see is in UE4 and they just check a “hollow” box but I can’t seem to find it in UE5
They are using the geometry brushes, I wouldn’t recommend it, not easy to work with.
Much better now, in 5, is the modelling mode.
- Make box
- Copy the box
- Make the copy slightly smaller
- Select both and use the boolean mode to chop one box away from the other
( I chopped the top off so you can see )

Clockwork Oceans instructions are excellent. Reminds me of this post I made.
Important point being is that objects will scale from their pivot points, so if you pay attention to pivot location, you will be able to scale the smaller box and achieve 
hollow box perfection !

Yes, the default pivot point of the box from the modeller is at the base, which means you need to move it up a touch to center it…

Hey there ClockworkOcean. Does this method work with imported 3D models? I imported a basic log cabin into my map with a door and some windows, but am unable to enter it.
That’s a collision issue, you have one big box around the thing.
Easiest way to fix that is
- Change the collision settings to ‘use complex as simple’
or
- Turn off collision altogether, and just put blocking volumes in
