Changing Helm Models

[Deider]

I assumed this would be easy - I've used CopyItemAndModify (or whatever the function is called) successfuly on clothes and armor. But when I try in on helms to change the model from one to another, nothing happens - no second helm is produced.

Anyone else had any success with this? There's a parameter in the script that is ignored for general items (aka not weapons or armor), and my guess is that perhaps that's the issue, but I could be way off. Any ideas?
