Garee,

The UV coordinates are saved as floating point numbers, that are (usually) from 0.0 (top-left edge) to 1.0 (bottom-right edge).  When the value is > 1.0 or < 0.0, software wraps it around so that it essentually changes to the 0.0 to 1.0 range.  This is also how actual 'tiling' texturing works... the software grabs pixels until it reaches the 1.0 edge and if the next value is greater than that, it simply wraps back to 0.0.

So, in effect, it doesn;t really matter if these 'islands' of UV data are in the (default) 0.0 -> 1.0 space, or outside of it somewhere.  As long as you use even multiples of 1.0 (positive or negative), they're all treated the same.

The attached image shows a model set up this way in UVMapper Pro.. I simply zoomed the view out far enough to see the other tiles.  When you go to make texture templates, you probably want to move it back into the 0->1 space, but this would be more of a limitation of how that feature works (to get the white background, etc).  I hadn't verified this, but I'm guessing that it won't save a template for out of bounds UVs.

You end up with the exact same number of textures applied.  Basically, what I do is create UVMapper 'regions' for each island (one for face map, one for torso map, etc) and include whatever materials are used for that island.  Then you can select these 'regions' and move them around (I'm not sure if UVMapper has an easy way of doing the tiling though.. I use BodyPaint and my plugins for it).
