I have most of my project's creature mannequins working! However, Lord Vivec is standing at attention instead of my preferred pose for him, his levitating meditation. Any idea on how to force this animation in a script or in his settings?

You could try looking into the various Anim- functions (PlayAnim, SkipAnim, etc.) in the MSFD. Did you put a new script on Vivec, perhaps one with a "SkipAnim" call? That would cause him not to meditate.

I cancelled the SkipAnim instruction in my creature mannequin script (which also has been attached to my Dagoth Ur, Almalexia, and Vivec mannequins) so they would look more alive. What is the MSFD?

PlayGroup, Idle2, 0

That should make him do the meditate animation.

Thanks! He works!
