Not yet.  There are texture converters at Daz that will allow conversion of textures from one figure to another. But the V4 to V3 one is still in development.

dphoadley has a remapped V3 to V4 in his store that will allow you to use V3 textures on V4. But currently there is nothing that will go the other direction.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
