Use

Now when on the Dynamic Lighting Layer, GM’s can select a new type of line to act as a Barrier known as “One Way”.
When a line or shape is drawn when this input is selected triangles will appear near the line letting you know which way light and vision will bypass the barrier.
You can also toggle the direction using the button in the submenu.

For those looking to add barriers as they know them now, they are still the default option and are listed as “Walls” in the submenu. All your currently applied lines and maps will default to this automatically.
