In-game Models
 

I am using the newest version of the item editor and I was wondering if changing the item icon changed the in-game model as well? If not, how do you do it? I don't want a good looking graphic for a sword to have a poor model :P

Nope; The Icon Wont Affect Anything In Game Other Than Its Icon...

To Change The Model (With Georges Stuff) you need to change the model ID in the "IDfile" field on the bottom left of the Editor panel... George also has a model viewer on his site... you basically replace the numbers in front of IT to change the graphic
