Don't forget that you have to change each texture map for each item.
In the material room, assuming that
Posette is figure 1, to the right select body. Then notice that under Preview, each part of the body is listed and each part of the body has a texture map associated with it. Select each one and change to the texture map you want to use. Change the preview also, so that when you are in the pose window,
Posette will look like you want her to.
I don't know of a way to change all of the body maps at one time, but this has worked for me.
