Why does Motor6D affect me if I weld manually?

Literally, I have tried EVERYTHING and I’m so unbelievably frustrated and done. Why does Motor6D affect me if I use RigEdit to weld my models?

I made a simple monster model for my game just to test some things out and I need to animate it, so I begin rigging it and I insert a humanoid and basically everything you know that ya gotta do to make a rig. Anyway, after rigging it and fixing up the joints, I go to the editor and every single time, it’s literally the same thing. I look up videos, stuff on the internet, and the past forum posts aren’t helping at all so, can someone please tell me what in the actual pain is going on.

please someone. end my suffering. help me please.
i feel like it’s a simple answer too and i’m just overthinking or something, anyway, please. someone.

Does RigEdit use Motor6Ds?

The error seems to explain itself.
In your Explorer window open up both the UpperTorso and LowerTorso listed in the error. I’m guessing you have more than 1 Motor6D joining them.

I do, sorry I don’t seem to quite grasp the situation with that though, does have multiple Motor6Ds joining one part cause a problem?

If you have more than 1 Motor6D in a Part connected to other Parts no (say the upper torso connected to the left and right arms and the head then no.
If you have 2 Motor6Ds connecting identical Parts (the UpperTorso to the LowerTorso) then they won’t work properly.
