To implement skins into the PS client, u first need to convert the skins to dds. (Linux users try Kolour paint or gimp) then go to where planeshift is installed. In the folder art there is a zip file called characters.zip. Add the dds files to the folder called enkim or enkif (depending if the skin is male or female) it and it will replace the original skin and therefore implement the skin into the game. I have took the time to convert the tasmanian skins into dds. here they are.

These tutorials are great for beginners, i hate to say it but it didnt help me that much because, well i already know how to do it. But i would really like to donate a 3D mesh someday soon so thnx for the encouragement. Sadly i can not join the PS team since i am a lot younger than 21. Good Job
