@Nanoglyph True, although getting people to read the instructions is another matter… Having separate UV files available for appending might be a better idea, but yeah some poor soul would have to make (and maintain) them in the first place. I did actually start making an alternative one a while back, with the idea that textures with similar configurations could be warped to match.
@calanir Yeah I think the banding was a separate issue. The creases followed the topology when using subsurf, hence why I presumed it was being caused by the weights. It was most obvious with multi-directional deformations (rather than e.g. a bending cylinder), so expression wrinkles are a good way to highlight the problem. There are also demo files in my other thread if they’re of any use.
@MichaelBenDavid The heads are all shape keys, mixed with Blend from Shape with “Add” unchecked. Sliders/New Shape from Mix is additive, which is not what you want.
On that note, if it were possible to blend shapes with the sliders in a non-additive way as well, that would be extraordinarily useful I think.
