Multiple UV's on one Mesh

[Casper]

I have a single mesh for a character, and the tutorials break down each part of UV mapping into seperate parts. Are these attached?How do I seperate out my UV so I can have a detailed face pelt and a less detailed pair of pants? Is this advisable.
My current fix was to clone a seperate head and create a UV for that but alas when lading back the UV to the main mesh it doesn't load.
Any help as to this process?

are you talking about your model is attached or the image is attached? If it's your model then you should never attach them before you texture them first rule of thumb Casper.

If your talking about the images then all you have to do is go into MS paint and use the selection box and sperate them and open a new file and save them as sperate images
