Hello guys! I'm trying to implement a smooth **getting up from ragdoll to animation**
----------
I have:
-------
1. **Generic rig** (Humanoid does not work
correctly, thanks to my 3d artist)
2. Only **blend tree** in animator (idle, move left, move right, move forward, move backward).
----------
What I already tried to:
------------------------
1. Do not disable animator, just transition to empty state
2. t value in Lerp (from 0 to 1) work smoothly, no big steps
3. Instantiate a copy of my character right before cache bones to check that bones cached correctly
----------
I Actually know how it works:
-----------------------------
1. **enable ragdoll and disable
animator**
2. **cache all rigidbody
bones**
3. **disable ragdoll and enable
animator**
4. **start lerping from
cached bones to animated bones in
LateUpdate**
----------
**It's work, but not completely**. There is a awkward **teleport in first frame** when blending is started in LateUpdate
----------

Here is my code with syntax highligthing

**PushHero() is entry point method**
====================================
Or the same code below
private void LateUpdate()
{
if (_isLerping == false)
return;
_lerp += GameParameters.Instance.StandUpLerpRate * Time.deltaTime;
for (int i = 0; i < _allRigidbodies.Length; i++)
{
_allRigidbodies[i].transform.localPosition = Vector3.Lerp(_fallenBonesPositions[i],
_allRigidbodies[i].transform.localPosition, _lerp);
_allRigidbodies[i].transform.rotation = Quaternion.Lerp(_fallenBonesAngles[i],
_allRigidbodies[i].transform.rotation, _lerp);
}
}
[ContextMenu("PushHero")]
public void PushHero()
{
_characterController.enabled = false;
_animator.enabled = false;
ActivateRagdoll();
_pushBone.AddForce((-transform.forward + Vector3.up) * GameParameters.Instance.PushForce,
ForceMode.Impulse);
StartCoroutine(ReturnToIdlePositionAfterSleepTime());
}
private void ActivateRagdoll()
{
for (int i = 0; i < _allRigidbodies.Length; i++)

_fallenBonesAngles[i] = Quaternion.Euler(_allRigidbodies[i].transform.localEulerAngles);
}
}
private void ResetArmatureToZeroAndMovePrefabToArmature()
{
var armatureGlobalPosition = _rootBone.position;
transform.position = armatureGlobalPosition;
_rootBone.localPosition = Vector3.zero;
}
private void DeactivateRagdoll()
