As you can see, it adds a new bone to the mesh that I don’t need or want.
I have turned add leaf bones off, I set the scene scale to 0.01, and I parented the bones with weights. Does anyone know whats going on?
I haven’t dealt with animation from blender to unreal in a long time but isn’t that just your armature? As far as I know it doesn’t cause any issues regarding animation.
I did a quick test and see the screenshots below. I just have a single bone but named my armature and the bone something different to see how it imports into Unreal. While there is only one bone Unreal gives me 2 bones to select which affect the model.
when you go to export from blender, on the export settings select armature then uncheck add leaf bones. adding leaf bones basically adds an extra bone to the end of all bone chains.
