Adding sets to Season 3.

[itaialroy]

So I was experimenting with adding items to my season 3 server, and I've got a problem.
Trying to add a Brave Helm to my server, I added it in the right place (46) in item.bmd and item.txt.
Then, I downloaded a season 6 client, and took Helmmale47.bmd and added it to my client in the right place (data/player or whatever).
When I /drop the item ingame, I don't see anything but the name on the ground.
If I pick it up, it just dissappears.
Can anyone provide any help about that?
Thanks in advance.

Now problem is different. the item is in my inventory, I can see the defence and all the info about the item
but I can't see the set itself. it's just blank, no picture, nothing.

create a dll source for lead extra item textures, than everything will be okey, you can check this method in the zteam s6 source, - client source.
