Okay, I'm not a good animator by any means but I just want to add a saddle bone from the horse skeleton nif to another skeleton nif in skyrim.

I've looked for about 3 hours now for a tutorial that I can follow but everywhere I go they seem to have jargon that I don't understand or skip steps and assume I know how to fill in the blanks myself.

What i'm asking for here is either one of two things:

-A link to a complete tutorial on how I can get a saddle bone from the horse skeleton onto any other skeleton already present in the game.

OR

-Someone to write up said tutorial for myself, and anyone else who may be in the same situation, right here.

What I have in terms of software and assets at the moment are as follows:
*The complete skyrim 'meshes' bsa unpacked
*Nifskope
*3DS Max (never used blender and never tried, only ever been taught in 3DS)

Thanks for taking the time to read this post and I look forward to any responses.
