Lucius Hair Join Problem

Patroklos

I have been playing aroung looking at the range of skin tones I can get.

After applying a morph, such as the Youth Morph, at the top of the forhead I get this lighter and/or an obvious join area with the Lucius materials no matter which of 4 hair materials I use.

This has not happened with any of the other character materials I have tried so far.

Has anyone else found this?

Any idea why it is happening?
