How do I assign a mesh to a body part?

[huntsman2310a]

hey guys

 

I'm having a bit of trouble with exporting NIFS.

 

for some reason, it always says that some parts of the mesh, namely the parts I have added to it. Aren't assigned to a body part, specifically Upper body 0. How do I assign them to these body parts?

Look in the vertex group menu, you will see some that start with BP_, like BP_HEAD, BP_TORSO, etc. In edit mode, pick the one you want (vertices are probably already highlighted by the export script) and click assign. Then try exporting again.

If those groups aren't listed, add them manually.
