User error, or bug?

HI!!!
I've been trying my damndest to learn to map. I was curious though, I thought you could select faces, name them as a sub-domain, then edit just those faces for a texture. Example being, if you're creating an etched glass, you obviously don't need the whole glass flattened out, you may only need one section of the glass for it. the only thing is, that to go through and choose tonnes of polygons just to get the area you need, is such a pain, i'd rather define the sub-domain in hexagon. when i import into carrara as a carrara file, it sees the sub-domains, but when i try to select by sub-domain name, it ignores it. So when I finally went through, selected all the faces i needed to create my sub-domain, and then went into the UV editor, the entire glass was there. I only wanted to work with that one section. And as for trying to unfold it, well, that's very difficult.

I'm also curious, why is when you change the colour of the whole object, can you not get the sub-domain to display it's own color again? Even when you change the whole objects shader to nothing again, they still don't change. The whole object is still one solid colour.

I think this is 100% user error, but any help would be great.

Are you naming selection or applying shading domain? To unwrap the model, you'll need to use shading domains.

I do not reconmend on UV unwrapping a portion of the model over the whole thing. Because, the seams of where the UV map ends will have a different look against the rest of the model. This is true with bitmap texture and with procedurals. So, if you were to unwrap, unwrap everything visible on the object at least, if not the whole model.

I've put up several tutorials on UV mapping. My website is www.awbenson.com and you should do them in order 1, 2, 3 and 4 because each tutorial builds up on what you learned on the prior tutorials.
