Yeah they are impressive, unfortunately they are not free :o( but worth while getting.

They have different mats...i think that one is 'chaos' or something like that and different morph settings. I parented them to the shoulder and used a freebie V3 pose to set the body. This also changes the pose of the wings. Experiment with the morphs they give and other V3 poses, including the fairy poses. They have interesting results, I am working on a flying one of the fairy poses now I will post it soon I hope.

Good luck and enjoy.
