Rig Doctor

Your character rig shouldn't take hours to diagnose.

Rig Doctor is a Blender addon designed to quickly find and repair common character rigging and weight problems.

Instead of manually searching through vertex groups, weight paint, and mesh transforms, Rig Doctor scans your character and shows you exactly where problems are.

Scan. Diagnose. Fix. Verify.

Rig Doctor can detect common problems such as:

• Zero-weight vertices
• Vertices with more than 4 bone influences
• Unnormalized vertex weights
• Empty vertex groups
• Unused vertex groups
• Missing bone groups
• Unapplied rotation
• Unapplied scale
• Negative scale
• Mesh and armature transform problems

One-Click Repair

Found a problem?

Use Fix Everything to automatically repair the problems that can be safely corrected.

Rig Doctor then performs another scan so you can verify the result instead of simply trusting a "Fixed" message.

Before

A character can look perfectly normal until you start posing it.

A single bad weight can cause a hand, arm, leg, or other part of the mesh to deform incorrectly.

Finding these problems manually can take a lot of time.

With Rig Doctor

1. Select your character.
2. Scan the rig.
3. See exactly what is wrong.
4. Repair the detected problems.
5. Automatically scan again.
6. Confirm that your rig is healthy.

Built for Character Artists

Rig Doctor is made for anyone who works with rigged characters in Blender and wants a faster way to check their characters before animation, export, or game-engine integration.

Whether you're preparing a character for animation or exporting it to a game engine, Rig Doctor helps you catch common rigging problems before they become bigger problems.

Visual Problem Detection

Rig Doctor can highlight problematic vertices so you can immediately see where the issue is on your character.

No need to search through thousands of vertices manually.

Designed Around a Simple Workflow

SCAN → DIAGNOSE → REPAIR → RESCAN

The goal is simple:

Spend less time hunting for rigging problems and more time actually using your character.

Important

Rig Doctor is designed to safely repair common weight and rig issues. Not every rig problem can or should be automatically changed, so the addon reports problems that may require manual attention rather than making potentially destructive changes to your character.

Requirements

• Blender 5.0+
• Rigged character with an armature
