this is my simple way. you have to downlaod a model. [under abilitys] take an orb, like orb of fire and change the fire orb model to the weapon model you want to use. make the weapon item and give them the abity you just created. it apears in their right hand (default) if u want it to appear in their left hand make the attacment point (hand, left)
second create a custom abilty base it off the item abilty armor bounes(+1) then name it whatever you want for examble lets name it sword next remove the editor suffix +1 next on Art-Trget click "add model" then chose the desired model next on art-target attachment point 1 click "add string" Then type it where you want it to be like as "hand" then "right" then on art-target attachments put 1. also uncechk the stats-item ability. then aseing the ability to the item or charecter. if you still do not understand you are beyond help and should not be making maps.
