Suppose I have just created a ~.blend file, and I want to include in the file a copyright notice. Two ways I can think of to do it off the top of my heard are to create a plane mesh object, and assign an image texture to it, where the image is a copyright notice; and to create a text object, where the object itself is the copyright notice. I'm sure if I think about it more, I can come up with several other methods, too.
Is there a recommended or generally accepted way to put a copyright notice in a Blend file, perhaps in the file's metadata?
