I am following the tutorial for making clothes meshes exactly, yet everytime I get to the end of the 40 steps and open up my final product in bodyshop it is invisible (see picture).

The icon is there after part 4, so I know it is okay until then, but at the end it too turns up invisible.

I am using milkshape to edit the top (it is a teen female top that I am trying to make longer so it actually covers the belly) and SimPE version 0.40

This is getting extremely frustrating. Hopefully someone can help and tell me what I am doing wrong.
