Auto-rigging
Software that fits a skeleton and skin weights to a character for you
Also called Automatic rigging
What is auto-rigging?
Auto-rigging is software that adds a skeleton and skin weights to a 3D character for you. You mark a few points, such as chin, wrists, elbows and knees, or let AI find them, and the tool fits the bones and binds the mesh. It saves most of the setup on standard bodies.
Think of it like this
Like an adjustable dress form: set a few measurements and a ready-made frame shapes itself to fit the body you give it.

Rig: Adding a skeleton and controls so the model can move.
How auto-rigging works
- 01Open a character mesh standing in a neutral T or A pose.
- 02Mark key points like chin, wrists and knees, or let the tool detect them.
- 03The tool fits a standard skeleton and calculates the skin weights.
- 04Test a few poses, then fix any joints that pinch or tear.
Auto-rigging vs manual rigging
| Property | Auto-rigging | Manual rigging |
|---|---|---|
| Time | Minutes | Hours to days |
| Body types | Mostly standard humans and animals | Anything, including odd creatures |
| Control | A fixed bone layout | Every bone and control chosen |
| Skill needed | Low | High |
Auto-rig standard characters for quick results, and rig by hand when the anatomy is unusual or custom controls matter.
Where auto-rigging is used
- Getting a scanned or AI-generated character moving fast
- Prototypes, previs and background characters
- Putting motion capture or library animations on a new model
Beginner tip
Pose the character with arms and legs clear of the body before auto-rigging. Limbs that touch the torso confuse the weight calculation, and the skin sticks together when the character moves.
