This is a little sample - on the left is the original (from the P4 female template), in the middle the Poser .bum conversion, and on the right the re-conversion by the filter. You can see that it is different - it has less contrast and a slightly different gradiation curve. If you have very large near-"plain" areas you will also get some of the shades that I mentioned. I'm still very happy that it works *that* good... :-)
