And a test of the same thing as before, but this time with selective
blurring in post-production using a matte pass of the transparency map
on its own.
This completes the effect of transparent, refractive skin. (Think
transparent fishy... if you look closely at one, their transparent
areas share a similar effect.)
I do wish XSI had a blurring node in their "Image Processing" set,
though. :/ It would have made this easier.
