Tony, you're the strangest person I've ever met on a forum, you know that, right?

I don't know if it's a cultural differences thing, but for some reason it always feel like I have to walk on eggshells when I discuss this stuff with you on the forum.  I'm having to do that right now, and all I did was post my opinion on how I'd go about doing what Teyon is asking for opinions on doing - stuff about the UV's!  If you're not really suited to making figures, ok, but it's not as if my post was trying to get you to make one!

Anyway, seeing as you're so good at fixing things, get on with fixing the splitting on Roxie that would not be there if it were not for stupid "seams" - and I'll get my Roxie to send you a big wet kiss if you fix it!

U have Blender.
Re UV map her into a single 8192x8192 map.
Maps nor UV's are Roxie's real issue.

if you get seams in your renders be sure all maps are loaded at Crisp.
Seam issue solved.

Just pointing out, I sculpted Rex and Roxie, technically, Darrell built them from the sculpts I did. :)  He should get more credit for that. So I like repeating it whenever I can. Those were more his babies than they were mine, since he rigged them too. 

@TheCrazyMeshDoctor - AKA Vilters
I'm talking about the seams when the body splits, not the textures, so fix it man, you bloody well fix it right away!!!

@Teyon
Well you both need a bloody good arse kicking for splitting the body panels up like that ;-)

 Hey Pumeco, never attack individuals please.

Stick to facts, and stay objective. 
Talk about companies, SM, DAZ, Hivewire, and give factual arguments as to HOW and WHY some things are what they are, and how to improve.
And when somebody does a good job, say so..

"Hey Pumeco, never attack individuals please."
Argh ... what!

"Stick to facts, and stay objective."
Ok, you make the scariest faces I've seen on Poser figures, Tony, but I think making the lips fatter would be a good start in improving the situation!

"Talk about companies, SM, DAZ, Hivewire, and give factual arguments as to HOW and WHY some things are what they are, and how to improve."
Well, ok then, I think SM are a bit too pushy and I think DAZ are a bit too incompetent (you did ask).
Regards Hivewire, no comment because I've never used them.

"And when somebody does a good job, say so..."
Teyon rocks at sculpting, Tony rocks at fixing things ... as I've said a few times!
