  4. Hi. I've tried to build rigid body and the extra nodes. The rigid body is placed CG of a car. The extra nodes are placed in several nodes on fixed position of a seat inside a car. I make imposed velocity, with its rigidbody, x translation (in my case translate backward), and LCID i integrate from acceleration-time history. I try to crash the seat into the box. However, when i look the result animations, only rigid body and the extra nodes moved instead of the whole seat Could i move the whole seat by only create imposed velocity of rigid body? Thank you for your help. Attached the model of the seat picture
