I am in the process of setting up an FTP site so that the model in question can be downloaded. Meanwhile, I will attempt te textually describe my situation.
The model described is rigged as per the section “Rigging a Hand or Foot” in the Blender 2.3 documentation.
The mesh of the fingers does not accurately follow the position of the bones. When curling a finger, the bone moves but the mesh will follow only a percentage of the bone’s displacement and not totally enclose it.
It is difficult to accurately pose the hands under these conditions and any help is greatly appreciated.
