I have a mesh tshirt template that I have created many shirts with. My dilemma is that there is a bottom piece that I am not sure how to use. The template is in png. format. At this point, I normally upload the png to my inventory and then create a new shirt in appearances and add the texture. When I try to do this, it puts the piece at the neckline instead of the waistline. I am using the current sl viewer which does not allow additional pieces to be created, so I have to make this as a seperate piece. What am I doing wrong?
