Hi Christopher,
The Torso track shows the keys of the following bones.
( "RL_Hips", "RL_Pelvis", "RL_Waist", "RL_Spine01", "RL_Spine02", "RL_L_Ribs", "RL_R_Ribs" )
If you are trying to change position of a character. I think “RL_Hips” is the one you are looking for.
Please ref to the attached sample code, and see if it helps.
