Blender Animation - Bones are "disfigured" or weird positions

The more time I spend using Roblox Studio, the more I realize it’s a poor program for developing video games.

I export my animation, but some bones appear in strange positions, causing it to look disfigured. I don’t know why; I tried using the keyframe baking and changing some properties in the export menu, but nothing fixes it.

PD: When exporting to FBX, additional bones called “end” appear.

How it should look (Blender File):

How it looks in export (FBX File, extra bones called “end” appears):

How it looks on roblox:

FBX export is honestly pretty bad; actually, no, it’s AWFUL. You can instead use the Animation Exporter plugin, and before you say anything, YES, it does support both bones and Motor6D or both at once. I’m not sure if it supports bones right now natively or not, but I have found a pretty interesting trick that lets you do that.

Ok, i’ll check this. And you have reason, FBX exportation are so bad.
