Is there any way that I can make my characters face into a race that you can choose through the Reflectron face constructor? This would be of great use to me, any help is appreciated.

The way i do it is use FNVEdit to copy a preset face like CGPresetCaucasianF01 for example to a new file. (They are listed under Non Player Character.)Then you can edit it in the Geck or if you already have one you like as a character you can use http://www.newvegasnexus.com/downloads/file.php?id=35769 and copy the data into the facegen data area of your new preset.

How do you do this? I'm very new to all of this.
