the extra layer arround the body(the dress) has its own TXMT(material)settings.
You find these in the recolor packages.
In the txmt you will see 2 lines,
stdMatBaseTextureEnabled(wich allows you to cut away parts) and stdMatAlphaBlendMode(wich allows you to cut away parts and make the layer transparant.)
In your recolor the first is enabled
by setting it to 1 instead of 0
