In the folder Ranny you'll see files named in Polish that are the same as gostek files, like Udo (thigh), Noga (shin), Klata (torso), etc. With new alpha-PNG support, you can open the ranny files up with PS, GIMP, P.net or equivalent and reduce opacity/transparency to the desired level and then save it as a PNG. Don't forget to CtrlC and V the folder Ranny into Team2.
