set attachment

Hi, im new here and i got warcraft tft and i want to import weapons and replace them for normal weapons but i dont know how 2 do it

1.You will need to export the models whose weapons you want to remove, use a model editing (I use Mdl Vis) program to remove the weapon's mesh and import the weaponless model back in ot the game.
2.You will need to import the weapon models you want, create abilities(based on slow aura or item damage bonus) that have the weapon models as attachments(attachment point weapon) and add these abilities to the units to whom you want the aproprite weapon attached.

It is possible to import models to attach them to other models, but what isn't possible is replacing parts of a model with another. So, for instance, you could import a pike to give it into the hands of a footman, but then he carries lance AND sword.

BUT if you change the model itself, then you would delete the sword parts from the model and add the pike parts. There's no way without modeling. Are you experienced with geomerging?

ah thnx i got it but i got rifleman and i want a another weapon does it then have 2 guns or dreadlord he doesnt even have a weapon

Ye rifleman only WITH modeling (because he already has a model), weapons for the dreadlord can be attached via aura to the attachment point "hand,left" or "hand,right", like WhiteDeath said.
