If you do not want stock pose files to turn the figure (and you should not) do not use hip to rotate the the figure on the Yaxis and do not use the trans dials on hip to position it on stage. Use BODY for both of these. Body dials do not get saved to a pose file, so additional poses will not rotate the figure from where Body has it. You use the rotations in hip to position the figure relative to the horizon with the hip front at zero to the front camera. Use the ytrans on hip to get it on the floor. Apply your poses to a figure, remove the values on the hip trans and any Universe Yaxis rotations and save the pose back to the library. Saving your scene as a PZ3 will preserve the Body position values.
