:) Thanks for the responses all. I have be doing these little 'cheats' all along and I don't know why, but this morning I just started thinking about it. Was I being lazy or doing what I needed for the image.

I don't know why I was thinking about this in a different terms. Like the movie set example, which was perfect, nobody else sees the background. I think this all is because this is the first time I have actually seen my flaws. In normal or 'classic' 2D works if you don't see it, it doesn't exist. Being new to this 3D world stuff this is the first time I have actually seen the flaws in the background. Sure nobody else can see it and I can see now that is the point. :)

So I will just keeping one doing what I am doing. Try to fix it up the best I can first, but if not able to do so, I won't worry myself. Thank you all again for your responses. It is good to know that this is something that is partly of how things are done, even if it is just to a small extent. :)
