[Help] Display Id Changing

[Netrizhul]

Hi
I'm new here and making server.
I'm using noobpack of Mangos.
I have a question to ask. :wave:
It's possible to change Display id for change item display. I mean I want to see Lightbringer T6 set look Judgement Set or something else.
I changed display ids of Lightbringer on my Mangos Database but everytime I enter the game. I see its not changed. I Tried to delete cache. Didnt work.
When I make a item from wow-v it say Display Id. I made a weapon which look like Corrupted Ashbringer. It worked. But when I change Display Id of normal items nothing change. Only can we change custom item or Do I a mistake?
Thanks

I believe the items already ingame(non-customs) are hardcoded to that item so it isn't possible to change them, that's also why custom items show up as a ? on their icon.
