So this isn't that much of a tutorial, because the method of doing this is very simple.

First grab a race model from patch-3.MPQ
convert it with mdmod3 to an m2i
import it to blender.

now take an existing geoset (Doesn't need to be the whole thing).
Just make sure when you don't grab something like a feet geoset for gloves or something.
You want the bones to still work.

If you feel you can re assign the weights then go right ahead

Now once you have your new geoset modified from the current model you took the verts from
or you created a new one.
Take a look at a geoset of the same type, such as if you are making gloves take a look at a glove geoset.

Now you should see something like this below (Depending on your current layout)


Simpley copy the number of the highest value in link and materials.
so say we have in example ME:Submesh#  and   OB:Submesh#    where the # you want your new geoset to have a value higher than the highest one of that group / geoset type.

So where you see in the picture I would change the submesh number to 1803 in both fields instead of 1802

Now export your model to an mdl and convert it back.
You now want to open it with pymodeleditor.
go to the geoset button and select your new geoset, make sure the geoset has the highest value of the same geoset type and write down the value or remember the number value it shows in pymodeleditor.
(DO NOT SAVE). you will break the model
and close pymodeleditor

now onto the itemdisplayinfo.dbc
In here you want to duplicate an item of the same type. so lets say you have a glove just duplicate the display id of an existing glove.

now go to field 8 ... or 7 if you are using taliis.
and change the field to the number you had in pymodel editor -1
so if you have 06 for the number in pymodel editor you would put a 5

and that's it save the dbc and create a new item in your database and throw the files we edited into
a new MPQ and give it a whirl

O.k. I figured out how to add a new geoset and assign it.
NOTE:I have no idea if there is already a tutorial on how to do this.
I was hoping to contribute to the community by releasing a tutorial on how to do it, but currently am experiencing a lot of bugs.(Mostly cache related.)

If there is already a technique for doing this please let me know where so I can figure out what I did wrong.

but anyways here is a video of what I got sofar.
If you think you can help please let me know in this post.

Like I said its really cache related. but there are other problems aswell.

Edit solved
I will post a tutorial soon

Yes I have a new gossip_menu_option entry and one in gossip_menu
Is it possible that it isn't assigning correctly?

to my knowledge the beta is not accessible yet

What about coding an ooen mmo engine completly independend from wow everyone can use?  I try to focus this now for 9 years but noone seams realy have interest in this idea.
Fully custom scriptable client,  server infrastructure,  a nice  editor and a help/content community around it.
All free and open source.  if someone like this idea contact me.

I just don't have the knowledge to do this.
I would love to do something like that if I knew how.
But as of right now I'm just trying to see what I can achieve.

Awesome! But as Phantom says before me, I think you'll have heavy issues when you have the game finished (and halfway) because Unity isn't strong enough :/

Yes I'm mostly just messing around at this point. if it becomes an issue, I will convert the code to another engine.

Thanx man
I considered it. I guess its just because I know c# and prefer to use unity.
probably just because I know how to use it.

p.s. if anyone knows c# I am looking for people to help out.

np bro. I am still going to make the animated model. but have fun with it
