This is a simple model that I hope will be of use to people. Working on star wars scenes and environments, I wanted to include the iconic light walls that you see on the death star and star destroyers, however I could only find whole scenes, rather than the element and model on its own, so that I could place it where I wanted. As a result I made this, and I hope it will solve your difficulties if you are having the same problem.
There is no backing to this because, so the light holes are hollow, just so that light shafts can be rendered through them, which looks rather good.
There are no textures, but any white and black plain materials will give the right effect.
