Im suprised you found that, I spent a few hours looking at it and seeing if I could remake it, And I finally did, I didnt really love Ashs (Was It ash that made that tut?) way of making bullet holes, so I decided to find out an alternative. Unfortunately, It took a very long time to try to remake the big bullethole, I wanted to cut most of it off, because it didnt look good.
EDIT: Now that I think about it, I think I found a tutorial, I must've got mixed up with something else, maybe My gallery title.
