Normalize UV Elements
"Normalizes the elements available in the unwrap-uv-editor according to its real 3d-surface-area.
Example: you've created two boxes...one big - one small...and unwrapped the faces....work...attach the boxes together. the uvs have the same sizes although the smaller box does not need such a big surface than the big box. The script resizes the elements so they are in a right way. ok? hmm...test it with a checker material :o)
This script works fine with max5...but remember that large surface-areas results in large uv-elements."
