glad to help
here are some of my settings if you really want to learn
Bump and mapping I feel add the most realism to a texture along with normal mapping but normal mapping is still very nice to daz so it needs better implementation
To create a bump map I take the texture and open it in any software that can let you change it to a gray scale map
trans maps are also black and white
displacement mapping is a bit different from bump mapping so it can be used along side your bump
when applying the bump map and disp map I like to set them
at 25, 50, 75 all the way up to 100
and them -.10 minimum and .10 max and then I change it up to get different results.
