How to create one-way mirror material

Hello,

I how do I go about creating a material that I can place on a wall that has one side of it see through like glass and the other a dark material you can’t see through. The things you see in police stations or for my case, to have them as windows for buildings so player can transition into the building first without seeing its empty from the outside but while inside player can see everything outside still.

Thanks for any help

Thanks man that worked for me, I had to change Lerp values on the opacity to 0.4 and 0.9 because that worked better for my setup but this is definitely the answer.
