I agree with you on the look of being lifeless in some cases, The model i used was an older version, they have a relay good just out model now of both man and women that is relay realistic including skin textures, the morphing that also comes with the new models allows more control over the overall look and fell, Unfortunately I can not afford the new models so have to work with the older ones, they have produced skin textures that you can update with the older models, but again you have to pay for them, it can cost a fortune.
I am new to doing the 3d stuff which i do with Daz Studio, I am practicing with using existing morphing and skin textures to get to more realistic look.
I am also doing skin painting at the moment which i can do on the older models to make them more realistic.
Thanks for the comments all.
