I thought that I'd share this info with the rest of the community. In case you did not know, the new characters Rex and Roxie have done something quite "creative" with their UV coordinates. There is a post about it here.

What they did was to offset the UV coordinates outside the {0..1} range for each map except the head texture. The purpose was no doubt to prevent them from appearing to overlap when viewing the UV's. They are relying on the fact that most programs will simply wrap the UV's accordingly.

However, some 3rd party texturing applications may not behave this way, and hence Rex and Roxie will not work properly. This was the case for realityPaint up until now. The latest update ( v1.0.4.1 ) will now prompt you when importing to wrap the UV's back into the {0..1} range if required.

The wrapping goes like this... if the UV's were { 0.5, 0.5 }, then nothing changes. For { 1.5, 0.5 }, they become { 0.5, 0.5 }, and for { 2.5, 0.5 }, they again become { 0.5, 0.5 }, etc.

Anyway, if you are trying to edit Rex or Roxie's texture in a 3rd party editor and you are encountering problems, then this may be the reason.

I hope this is helpful

I don't think that's the purpose. The purpose is that you can use a single image map for all the sections and just scale it to 2x2 instead of 1x1. This would be most useful for low-res maps in background characters.

Makes sense... in any case, something to watch out for.

It also works better for owners of Mudbox as opposed to our older way of doing things.
