(Paid) (Bounty) Issue with moving skinned mesh causing wrong position of skeleton

Jobs
1

We have noticed that when moving a skinned mesh, there is a lot of jitter. We found that it might be caused by the skinned mesh skeleton not having the correct position when moving the mesh itself. Here is a js fiddle demonstrating the behaviour. The camera is moving with the model you can see how the skeleton is offset from the model itself:

I know that with larger units there can be issues but we are dealing with regular sizes here of like 1x1x1. The weird thing is. This only happens when i throttle the shadow updates. If i let shadowMap autoUpdate = true its not broken

Happy to pay a bounty for fixing this problem: 250 USD

You can use this class with Mixamo animations, but I didn’t do anything explaining how to use it.https://didisoftwares.ddns.net/6/index.html

Hi. Nice to meet you.
When working with skinned meshes in three.js, it is not uncommon to encounter issues such as jittering during movement. This can often be attributed to the way the skeleton is updated in relation to the mesh’s position. Below, I will provide a detailed explanation of the potential causes of this issue and how to resolve it effectively.
If you want, let me guide you.
Many thanks.

We tracked this problem down to something related to shadowmapping.
