Alright so after a lot of confusion and trial and error I finally managed to port over the AN-94 only problem is the 2nd mag used to knock the 1st one out is invisible. Both mags use the same texture which I called mtl_an94
Here's the view model in Maya

I've Finally been able to port over the Boomhilda but have a problem with the scope is it something to do in assman? in Maya its transparent.

I've done everything correctly I haven't deleted any joints to mess it up and have done it correctly in assman but it still looks stupid.
