JohnSlayer sorry dude im no 3d artist im affraid, just grabbed this file of a friend and enlarged to suit Avadash.. I will ask him if he has the time to add some swords for you though..
Killazin corp if its the new version of Ava 0.49.1 the file goes in Media/Skins/default and rename to screensaver.x
if its the older version put in the Z cache and rename to screensaver3d.x
And remember to turn of the screensaver while you are uploading or you will have grief, once uploaded then enable the screensaver..
