Hello I'm new to the forums so please let me know if I'm in the wrong forum but anyways I'm trying to convert a dress from Adult male to Teen male but it's not coming out right. Am I'm missing something or am I not doing it right?

I've moved this to the Create forums.

What exactly have you done to get to this point?

Incidentally, instead of messing about with a digital camera, you can take a pic of your screen by just going to Start -> Accessories -> Snipping Tool.

I followed the steps in the video ( https://www.youtube.com/watch?v=qpKKNim6aYY ) but still not sure on how to convert clothing from Adult(s) to Teen(s) Etc. I took the photo with my phone.

I figured out the problem the Mesh has to be the same as the other item.

That's right. Sometimes you can get away with doing it this way if the meshes and texture mapping are close enough... but in a lot of cases, it's just not going to work (as you found out).

The best way to do age conversions is to make a new mesh. In this case, you'd take the adult mesh, resize it so that it fits a teen, and then put it into a new mesh package. It takes a while to learn how to do it, but it'll get the best results. (If you're interested in learning how to make meshes, I suggest working through the beginner tutorials on this site.)

Ok, I'll look into it.
