I want the interior of the rooms to look real from the windows of the office building I have prepared. It doesn’t seem realistic to place a bitmap on windows when rendering exterior.
There was a script for this. Depending on the camera’s direction, the interior image behaved like 3D. I couldn’t remember the name of the script.
Those parallaxx shaders are pretty amazing. One note though, unless you are rendering your shot in low light or even at night, you will not be able to see inside the windows.
