The slow motion is to try to hide the animation mistake
I did try to use the faster rendering engine with the Genesis 3 character but the results are so superior with Iray that its hard to go back.
Also i usually don't advertise their product but Daz got the ¨wet body Iray¨ for Genesis 3 that gave this result without too much effort on my part (its getting very hot under that sun that the poor girl is sweating all the water in her body can, someone gave her some something to drink for god sake...)
