When I characterize my model and make a character rig, the location of the ChestEndEffector (the control at the top of the spine) is not below the neck like it is in the sample models. Instead, it is down by my model's waist. As far as I know, my bones are named correctly (it characterizes) and the bones are placed correctly as well (in fact, they are exactly like the ElasticMan.fbx. I have attached a picture of where the Motionbuilder puts the ChestEndEffector (the green arrow points at the misplaced effector).
If anyone has any insights, please enlighten me! Thank you!!!
