Take a look at the x-ray renderings. Changing the angle does not introduce weird artifacts. Which is just why he is so suspicious of your image in #252. Can you give a test image (say of Barack Obama, since nobody on this thread is a fan of his), and tell us the settings on the filter you used to get the picture in #252, and we can see what Obama looks like under the artifact of the Photoshop filter?
Cheers!
Here's Obama, differing only the angle. The settings are different from the shroud. Every image needs to be tweaked to get decent results. The Photoshop filter isn't optimized for this kind of work. To do this well you would need something like Bryce 3D.
