One-way props allow you to see through them from only one direction. Think of it like a one-way mirror. Check with your server's rules before using one-way props. Some server rules allow this and some do not.

When choosing a prop for your one-way fence consider your base's layout, server rules, etc. Some fences can be shot through and others cannot, the latter will offer more protection but will require you to be exposed to face your raider.

Set Stack Direction to Behind and stack the prop however many times you want. The more props you use, the more difficult it will be for the raider to break through your fence using blowtorches or explosives, however using more than one fence will make it more difficult for you to see through.

Select this material for the inside of your wall. It’s the red liquid material & is transparent.
Apply it to the inside of your wall.



Next, select the black material (or any dark material which is not transparent) directly to the right of the red liquid material for the outside (this is the part your intruders will see) and apply it to the opposite side.

Change Render Mode to World Glow. Apply it to the black side.
When you’re finished your props will look like so.
