Probably this bug has been reported somewhere else already, but as I couldn't find any reporting nor solution, here a description of my problem: some advlt female characters in my game appear to have a blue/black face (screenshot below).

The only face-altering mods I'm using are FO3 Facegen Presets, Hi-Res Eyes Replacer, Improved Faces and Eyelashes New Vegas.

Any idea how to fix this?

Think I found the solution for myself in between. Just deactivated Eyelashes New Vegas (which probably caused a conflict with Hi-Res Eyes Replacer) and it seems to be displayed correctly now.
