First at all , I know nothing about animations in Poser,

I have a model (V4) and I apply a pose animation (aprox 60 frames) ok, this action  created 60 frames with v4 moving , but V4 is under the ground in all frames.

I can Up V4  to to the edge of the floor frame by frame, but I would like knowing how I done only once for all frames

thanks in advance
