There also used to be two sets of UVS files available for V3. (SEE LINK)

The first set remapped V3 to V2, but retained the V3 grouping, so you could still use V3s advanced material zones.
The second set remapped V3 to V2 and also changed the grouping to V2, so that default V2 MATS could be used.

As mentioned, the "V3ToV2" character is also remapped to V2 (but not regrouped), but you are stuck with the default V2 body shape, as neither V2 nor V3s bodymorphs are transferable.
(So the Netherworks "true" V2/V3 hybrid is a far better alternative, as it can use all V2 bodymorphs)
