Quote - I agree about UV maps taking up as much of the UV space as possible. But overlapping uvs are common in Poser. If I have a cork and a lot of different bottles to put a cork in, I'm only gonna model and uv the cork once. But every time an individual bottle .obj is opened, the cork is gonna be on top of everything else. I don't see a problem with that.

I don't know why people have so much trouble understanding UVs...

Okay, the standard UV space is 0-1, but there are also an infinite number of other tiles, call them 1-2, 2-3, 3-4, or u1_v1, u2_v2, etc.

There is absolutely no reason why Pose UVs all need to be stacked into 0-1. You could put the head in 0-1 and the body on tile u496_v127 and for all Poser knows or cares it's all still 0-1, since Poser only reads the texture information in a UV tile.

However, try to import that entire figure into ZBrush, Mudbox, Mari or Body Paint to do some texture painting, and it's not going to work, because those programs see them as overlapping UVs, not independent materials that happen to be in the same UV space. So to use Poser figures in those programs, you have to first manually move the UV groups to separate tiles or patches before importing.

If this were done when UV mapping a Poser figure in the first place, that would be one less hassle, and several more points for professionalism and versatility.

And it takes virtually no time to move a UV group to its own tile when UV mapping in any program worth its cost, Lightwave included.

It may be common in Poser, but to be honest it's just stupid that anyone did it that way to begin with and it's pointless to keep doing it that way. I suspect everyone here uses UV Mapper, which, I believe, just plops them all into 0-1 and gives the idiotic error message about UVs being out of range otherwise.

As I already stated, Poser does not care where those UVs are, as long as they're somewhere. It can't tell the difference between UVs in 0-1 or in 9-10 or anywhere else.
