So I opened up nifscope to see if I mash together something that would do the job.
I came up with this (http://i237.photobucket.com/albums/ff292/VonGrantoven/DartCrossbow2.jpg) which I am reasonably happy with, but unfortunately I can't seem to get it to load in the GECK.
The fact is, I am a nifskope noob when it comes to nodes and such.
I was hoping to find a nifscope master who would be willing to have a look at the .nif file and see if they could find out what the problem is.
I'm sure there are lots of raiders who would be eternally grateful for any help in getting this working!
