It is a common mistake when you export one group from Poser to make a "head" morph for example.
They export the head from Poser as a morph target.
Open it in Hex or any other 3D app to morph.
And accidently move the "whole head" instead of just the poly's they want to morph.

When they go back to Poser with their "morphed head" they find it a yard out of position :-)

Strange results.... :-) :-)

Maintaining the center in 3D space is part of the "fail safe" in the above procedure.

Happy Posering and happy morphing.
