Hi there

I´ve got a problem here. I am porting Cataclysm tophat (Lord Walden's Top Hat) to 3.3.5a Lich King. I followed tutorial about porting stuff but when i put my helm on, it´s just invisible and my character hair is cut.
Steps i did:
1. Extracted m2, skin files, bmp, icon from Cata mpqs
2. Moved line about stuff from Cata dbc to WotLK dbc
3. Opened m2 and skin, used template, edited nTexUnit and Cameras, copied ofsTexUnit from ofsTransLookup
4. Created new MPQ patch from these files.
5. Created item in database
6. Tested my invisible tophat

I should mention, that i already ported some NPC (fox, mastiff, ettin) and they´re working fine.
Is it even possible to port these things?
Sorry for my english. It must be painful to even read my post
