rotation is not smooth

ive got this rigid controller script, i need to do chest aiming rotation in lateupdate to override the animations, problem is it "snaps" to the rotation instead of being smooth. i tried using time.deltatime but then nothing happens at all. can someone give me advice to get the smooth rotation?

heres the code

Looks like you're using 'Time.time' - that's the time since the beginning of the game so it'll be a pretty huge value. That's probably why it's moving straight away. In LateUpdate you also seem to be using 'addVector' which I can't see being set up anywhere - is that declared in the object instance?

 

addvector is set in the editor cause my chest bone isnt facing forward in z axis.
what should i use instead of Time.time? if i use deltatime the chest doesnt rotate at all

 

Is the chest parented ? 3d game right? if so try unparent and move transform.

 

cant unparent, its a skinned mesh , its not a good idea to move the bones

 

ive found a workaround and it works fine now, ive parented a empty gameobject to the "hips" bone and made that object look smooth at a target with time.deltatime and then set the chests' transform to be the same rotation as the empty gameobject in lateupdate.
