I'm trying to port The Riddler from Arkham City to Garry's Mod, and to do so, I copied a male armature from Half Life 2 and parented The Riddler model to it with automatic weights.
I then went into Edit Mode and spent a long time assigning vertices to the bones (not many, as I was just testing) to make the rig more accurate, but when I went into Pose Mode with parts of the armature selected, they did not move correctly with the mesh.
I then parented a collision mesh to the armature as well (as this was needed), and that worked fine.
I'm very confused as to why The Riddler does NOT move in time, as I remember trying Automatic Weights again, with the same results.
Possibly an easy fix?
