Here is a screen shot of the issue…

The grayish square behind the head is an object I used as a background and is positioned so it wouldn’t be entirely behind the character so you can see when the hair goes in front of the background, it disappears.
On the transparency issue, it seams that putting lights in front of the hair resolved it but frankly, all of this doesn’t make any sense……bugs?
What do you think?
Thanks,
Brian
