[SELF SOLVED] Skinned mesh character animations not playing correctly

[Dosimpl]

I’ve been messing around with some animations on a website and it looks great and plays fine, however once imported to roblox studio a certain body part appears to be stuck when playing any animations, basically it’s not playing the same that was shown.

I’m not the best at skinned mesh rigs, So I’ve come here to see if anyone has any possible solutions to this. I’ve thought maybe its something to do with how the rig has been set up if so, Here is what it looks like:

If anyone read this and tried to solve it, I apologise for wasting your time as I managed to fix it by just using the Auto Rigger By Mixamo, Turns out the Main Armature itself would not fully import into roblox studio.
