I am trying to create a two-way mirror for an interior project, a recreation of an artwork in CGI.
The mirror should have to be like the ones in Interrogation rooms.

To do that, I have to make the mirror object single sided. But octane identifies it as 2 sided.
Would you advice me somekind of a walkaround for that?

I think its not possible for a physically correct environment Or is it possible? or will it be possible to create somekind of effect in later releases?

These mirrors reflect a lot on one side and transmit very small amount off light into the observation room.
I would a extruded plane, eg a 2 sided mesh like a squashed cube, make sure the sides on both normals point outward, then split both sides into 2 materials and make the ior index high on the side in the interrogation room, slit reflects a lot, and make the side of the interrogation room reflect less by using a lower ior.

What values to use will be trial and error as I have no clue how these things are built in the real world, but I think it probably uses a similar technique or uses a reflective coating.

Thank you radiance..
And sorry for my behavior about the message thing, You are right.

Will test your advices and post here
Hopefully I want this to be a overdriven trace depth benchmark type of thing.
