If you apply an image_map, image_pattern, or any image projection on a
transparent object ...
you will not have the same effect on an Hollow Cylinder .. or a Plain TUBE
..

you will see the image map 2 times on a plain tube ..instead of one on a
hollow cylinder ...


That what i have meant by talking about 'no depth' .... (note the comas) ..

I have compared a plain tube'  to an hollow cylinder ..... and not of course
a plain tube to hollow tube .which will kept the 2 image_map...
