How do I stop my weapon model from sitting in the middle of my player model?

So I’ve got this little melee weapon model, but it doesn’t attach to the arms for some reason.

I already made a custom model for it and put a ValveBiped.Bip01_R_Hand bone in it, still no success. Any ideas?

Nevermind, fixed it by using a skin modifier on the model :3:

You have to rig the model to the bone aswell.

He fixed it before your comment.

I put it incase someone else had the problem because they didn’t even slightly explain how they’d fixed it (whats a skin modifier?)
