Blender Rigify Rig Not Generating or Bones Misplaced Fix

In this tutorial, you'll learn about Blender Rigify Rig Not Generating or Bones Misplaced Fix. We cover key concepts, practical examples, and best practices to help you understand and apply this topic effectively.

The Problem

You create a Rigify metarig but clicking 'Generate Rig' produces errors, the generated rig has bones in wrong positions, or the controls do not affect the mesh.

Quick Fix

Step 1: Align the metarig to the character

Must match character position.

Wrong — metarig at origin, character elsewhere:

Metarig at (0,0,0) → character at (5,0,0) → bones in empty space

Right — align metarig:

Select metarig → G to move into character
Scale (S) to match proportions
Edit Mode → move individual bones to joints

Expected output: Bones align with character.

Step 2: Apply character scale before generating

Non-uniform scaling breaks generation.

Wrong — character has non-uniform scale:

Scale: (2, 1.5, 1) → rig generates incorrectly

Right — apply scale:

Select mesh → Ctrl+A → Apply → Scale
Apply Rotation and Location too

Expected output: Rig generates correctly.

Step 3: Check bone naming and layers

Rigify relies on specific names.

Wrong — renamed essential bones:

SPINE renamed to MAIN → generation fails

Right — use default names:

Delete metarig → add fresh Human (Meta-Rig)
Position it correctly
Only add extra bones via 'Chain', not duplication

Expected output: Rig generates with all controls.

Step 4: Parent mesh to generated rig

Armature modifier must target generated rig.

Select character mesh
Add Modifier → Armature
Object: select generated rig (not metarig)
Apply: 'With Automatic Weights'

Expected output: Rig controls deform mesh.

Prevention

• Apply character scale before generating
• Use default metarig bone names
• Save metarig position presets
• Test generation with default metarig first

Common Mistakes with rigify bones

1. Forgetting deriving (Show, Eq) on custom data types needed for debugging
2. Placing the wildcard pattern first in case expressions, making all subsequent patterns unreachable
3. Using head and tail instead of pattern matching, causing runtime errors on empty lists

These mistakes appear frequently in real-world BLENDER code. DodaTech's contributors have identified these patterns through analysis of open-source projects and production systems.

Practice Exercise

Write a pure function that safely divides two integers using Maybe, then test it with edge cases like division by zero and negative numbers.

This exercise reinforces the concepts covered in this guide. Try implementing it before checking online solutions.
