when animating in p7 why does the hair and teeth seem to not keyframe?

Can you be more specific?  Show a picture?

Are you animating a material setting or a 'movement' parameter?

Are the hair and teeth rigged as smart props?
Sometimes Poser has trouble with selecting a smart prop,
and P7 seems to be worse in this way.  It can be hard to
reach a smart prop on the selection pulldown menus.

But I haven't seen a situation where the smartprop
doesn't show up on the keyframe graph.

hair won't morph from one keyframe to the next? I'm guessing ya don't want the hair to change position in keyframes, as it's parented or conformed to the figure.

ok.  say my v4 figure has a hair prop.  She is in a sitting pose in frame 1.  Frame 30 her head is turned, or bent.  The hair sometimes does not move with the head. quite often the teeth don't either.  This is only an intermittent problem but annoying none the less.  
the hair is kozoburo messy scaled to fit v4.  The teeth are the v4 teeth.  When this occurs i can click on the head and the hair and teeth snap back into the correct position.  When animation is played back it does it again.  Other times it works fine

I appreciate the feedback.

 ockham thanks for all your great scripts.

I've witnessed this happen occasionally, when the Point At function is used.
