Ultimate Ripping Tool for Second Life - MeshFix v2

Yes my program doesn't keep skeleton data. It was made to rip items as they were easily and fast and comfortable, not modify them in blender (because modifying stuff in blender is the denial of "fast and comfortable ripping"). If you need to modify something in blender you should use MeshesSL or Mesh Helper. 

And about my software being too complicated.. well, I tried to make it easy and fast to rip stuff. If you have read the manual I have written and still have some issues don't hesistate to write about them here on forum. Me and surely others too will gladly help you :)
