As i said in your thread;
Simply: Copy EFlyff's model folder into your Resource folder, overwrite everything. Unpack their mdlObj, Mdldyna, and defineObj. Copy everything into your resource folder, overwrite. Restart server and check. For the items such as "Dryade" i suggest you doing following:
Unpack EFlyFF's Propitem.txt/.txt.txt, mdlDyna.inc, DefineItem.h.
Heres a male knight hat dryade set, just to show u what to look after. You should know how to add the rest into defineitem, mdldyna n such, else i suggest you to look after a tutorial on how to add items, then learn it from there. Its really easy and simple when you implemented your first item.
Although remember: If you define your item with a number which is too big compared to the last ID, your item will be seen as another item if you go out of sight of a character.
