I am working on something that I don't think has been messed with at all on eqemu yet - figuring out how to implement the new helm models from live, including pointy wizard hats, skulls, evil eye masks, and other such cool helms.
Within each eqg model for each helm, there is a range of IT numbers, one for each race, all sized differently.
Currently I have this "kind of" implemented by taking one of those IT numbers and assigning it as the model for a helmet item, but they do not scale properly, and don't really line up with each race as they are supposed to.
Sometimes they show up sideways.
I'm thinking these can be implemented the same way the velious helm textures were, where somehow you can tie "IT240" with "all" velious helm models, and they will scale properly and show up differently depending on the race. If anyone has some thoughts about this or wants to tackle this with me, feel free to shout, otherwise I'm just going to keep poking around...
