I was wondering how you get the codes for this program. The IDs for items work from wowhead, but model IDs from wowhead don't work. I really want Wrathion's ID and I'm having trouble finding it. The program is here: [Release] tMorph — 64-bit Morpher (with Panda support)
Wowhead ID's + AtlasLoot ID's work for items and many npc's. Thing is, there are like 10+ versions or each npc. You just gotta find the right one.
