Quote - That sounds suspiciously like a graphics driver/hardware issue.  What exact kind of graphics card do you have?  What resolution and color mode do you work in?  What version of drivers do you run?  Changing camera "fixing" the placement of hair and teeth really sounds like display to me.  Also you might check the parameter dials for the stuff that pops loose, and watch to see if the x/y/z changes when you switch cameras and "fix" it (I bet the numbers don't change).

Interesting idea.  I checked out my system and did a few more tests.  The graphics card I have is an NVIDIA Quadro FX Go1400 in a Dell M70 Precision Mobile Workstation.  It has the latest driver posted on the Dell support site, and it is dated March 22, 2006.  I've been running both P6 and P7 for these tests, trying both OpenGL and SreeD.  Thinking it might have been an issue with my now heavily-customized V4, I ran a few tests using an out-of-the-box V4 Basic.  Here's the interesting scoop:

Flying teeth happens after turning on Point_At for the eyes for:

V4 Basic in P7
V4 Basic in P6
An old customized V2 character in P7

It does NOT happen when I run the old customized V2 character in P6.

I also tried editing the V4 CR2 and actually deleting the jaw, eye, and tongue body parts and then parenting a set of eye props to the V4 head (and made her keep her mouth closed).  Result: still got flying teeth and prop hair.

Checked to make sure it all happened with Hardware Acceleration either on or off.  No apparent difference.

So given that it happens in P6 with V4 and with everything in P7, perhaps it is in fact a case where my graphics hardware is overloaded, though it seems odd since my customized V2 character is about 15 times the file size of the V4 Basic.

Not sure where this leaves me, other than thinking I need to either buy a new machine or go back to using V2 characters in P6... or giving up on animating in P7 or animating V4 in P6.  None of those are great options.

Anyway, thanks for the ideas.
