With with Maya 2008's UV Texture Editor

I'm having trouble editing the textures on my UV maps. No matter what I do to the UV coordinates in th Texture Editor, the scaling and position of the texture stays the same! UV verticies are selected, both in the 3D vew and the TE. Also, for some reason, the TE don't show my texture in that square even though it is set to Display Image. It just shows a gray square. I'm trying to texture a simple wall with 1 512 x 512 texture. I obviously have to scale it to make the square texture tile into the long, rectangular wall, but nothing I try works (or at least, nothing intuitive I try works). Right now, the texture on the wall is stretched and the texture in the TE is gray.

So what's the trick to get the TE to work?

Have you tried the unfold tool in the TE?

Thanks for posting. That didn't solve the issue, but I think I stumbled upon something:

This model has two UV sets - the original one didn't look right to me, so I simply made another. The original UV set still works and influences in the texture (well, part of it, but that's a whole other story).  Apparently only one UV set can influence the object at once? I don't know. If someone who's an expert on UV mapping can clarify how UV Sets work, that would help.

No, one uvset can only affect one texture node, but the viewports are just previews of a kind so they dont ncecceserily reflect anything specific about what you can end up with. Theres lots of things teh shadiong graph can do that would be too low for the hardware to do, so they dont attempt to either.

If your doing models for games then it doent matter much either since its actually very rare to need 2 uvsets at once unless you must layer some totaly unrelated stuff for final compositing. Wich in either case would be done by a shader, which you should expose to maya as a hw shader anyways to get any sane feedback.
