how to change model of the unit inside game with trigger?

[emil23]

hi i got a hero in map but i would like him to get diff model after he completes quest. he should save his stats skills and still be affected by future triggers in map. its a pre spawned hero in editor so many events are connected with him, so is there way to give him diff model with trigger? i heard unit skin a new thing could do that but i got no idea how to use it

native BlzSetUnitSkin takes unit whichUnit, integer skinId returns nothing
native BlzGetUnitSkin takes unit whichUnit returns integer

GUI:

• Actions
  • Unit - Set Unit Skin of Blood Mage 0002 <gen> to 'Hamg' // Archmage
  • Unit - Set Unit Skin of Blood Mage 0002 <gen> to 'hfoo' // Footman
  • Unit - Set Unit Skin of Blood Mage 0002 <gen> to (Skin ID of (Dying unit)) // this works too

Object ID can be seen in Object Editor by pressing Ctrl + D.
