There are without doubt free ones in the Free Stuff section here, make a search. If you want to buy, there are plenty. The DAZ V3 texture is very good. ByteMeOK sells excellent textures in the MarketPlace here. Definately favourites of mine, but you can find plenty of others. You can actually use V2 textures on V3 as well, there is a UV file on the V3 product page that you can use to re-map V3 to take V2 textures. There are instructions how to do that in the FAQ section at DAZ. After that you can use the many free V2 textures in Free Stuff.
