I need a one way window. People on the inside can see out, but the people on the outside just see a wall. Is this even possible? Thanks! Anth4598 EDIT: It seems I don't need a script to do it. I thought it might need a script, please don't give negative feedback because I didn't know. Also thanks for the answers, I will try that!
If you put a decal on one side and have the other side see though, it should work.
While this isn't exactly a scripting question, I'll answer this anyways.
Yes, it is possible to make a one way window. First, find an opaque decal of your choice. It can be your own, or from the catalog. Next, apply it on all faces of a transparent brick EXCEPT for the face that people can see out of. If you did this correctly, you will have a wall with one side a window, and another solid side.
