Recommended Weapon Export settings

[Gwyvern]

hello, its me again, im still working on trying to get my custom modeled weapon to work, and after some scouring the internet, have come up blank

 

but heres an idea that should be easy to answer, in the blender .nif export tools, what are the recommended settings for exporting a weapon? it uses existing vanilla textures so that shouldnt an issue, but maby i have somthing checked that is causing my <!> problem in the geck

 

so what are the recommended export setings from .blend to .nif for weapons?

 

thanks for any help!
