Sorry- hit return out of the text box and sent too soon. I have a lot of first hand experience with scars--have had lots o' surgery in 38+ years. Luckily none I can't cover with clothes :) Helen's comment about irregular width is a good point. The surgery scar on my chest isn't all that even in width or height, and many of the stitch marks have faded to near invisibility. They'd best be represented by a light spot or line on the texture map rather than in the bump. GrayMare
