Really need help with this!

Hi i’m Gio, a new italian “developer”. Im asking u guys to answer this. Im using the RigEdit Lite plugin, im trying to rig my custom character. However, im using a model to do the torso and i cant make a joint between the torso and other body parts. Then i found out that u could make joints only with parts, so i made another torso using only parts and then i created welds with them. But i dont know what to do now, i feel so lost

  1. Create character parts.
  2. Create Motor6D joints between parts.
  3. Adjust their positions to not be just in center.
  4. Rig done. Now go animate it or do smth else.
