help 3rd animations modding help

[trulypanda]

I was modding pa2haaim.kf and 2hafastforward.kf files with blender v2.49b,

However, weapon controlled blocks can't connect into skeleton with Nifskope and blender with animations,

so I have to change the properties and entered the game to see how exactly it actual looks with gauss rifle every time.

Is there exist smarter method to let specific weapon could be showed with 3rd animation as nifskope & blender? thanks.
