What is your problem exactly?

What program you use? I can help with blender.

Yep I'm using blender.

In trying to make the dark trooper phase 2 from the old dark forces mod build on jkhub onto the rocket trooper skeleton. Problem is that this skeleton is waaaaay to simplified and it barely resembles any other humanoid skeleton. I really dont know where too start

You made characters in blender before?

The idea is simple - You need to weight the character to the rockettrooper skeleton - bones to be more specific. Their names are different than basic _humanoid.gla

Check in the modview how bones are called by opening rockettrooper. You can PM if you need more help!
