I'm not much of an artist, but I reckon it shouldn't be too hard to create a scar for a character, a la this fine mod (
http://knightsoftheoldrepublic.filefront.com/file/Wound_in_the_Force;89578), if someone can point me in the right direction. I've googled for tutorials, but so far I've only come across lame methods that don't work or produce results that are really cheesy. I know I'd have to create an "extra mesh" so when I "put a scar on the right side of the head, it doesn’t show up on the left eye as well", but I figure that's another problem for another time.
Hmm... I didn't intend for this to be a modding request, just a request for guidance, so I guess I put this is the wrong forum.
