how to make one way glass

Question

I'm trying to make one-way glass like the one used in interrogation rooms. if you look at it from one side, it's a solid color and from the other it's clear glass, so only one side can see the other. Is there a way to do so in blender?

Thanks in advance.

Use the Geometry node and its Backfacing output as factor in a Mix Shader:

If you are in Eevee don't forget to enable the Alpha Blend option to have transparency:

If you give it thickness, select one face and invert it with AltN > Flip:

of course it can be a bit more complicated setup than just transparency (Glass, Glossy, etc) – moonboots Nov 20 '22 at 14:22
is there a way to do it if I wanted to add thickness instead of just a plane – Jo xXx Nov 20 '22 at 14:25
