Quote - -In fact, there's even one quite recent texture/character set that only includes shots of the second skin textures and not the main texture itself - it might well be a nice set, but there's simply no way to tell from the promos. -

Keep in mind that vendors have to apply certain rules while making the promos. An example that may apply to what you said above is an under age character package. Nudity cannot be shown anywhere in the promos unlike for adult character packages.:)

This ones's very definitely an adult character for V4.

In any case, even if full nudity is not an option, it's still possible to show close-ups of other aspects of the texture which can give a reasonable (if incomplete) idea of how good the product is (e.g. the various texture sets available at daz).
