Fix Bone Rig Deformations Like a Pro

When Your Bones Decide to Make Abstract Art 🎨

Nothing more frustrating than watching your carefully built rig turn into a nightmare of deformations. But before cursing the 3D gods, check these key points. Your model will be back to normal faster than it takes Blender to update its interface! 😅

"90% of bone problems are solved by looking at three things: weights, hierarchy, and orientation. The other 10% is digital black magic."

Weight Painting: The Art of Telling Vertices Who's in Charge

When vertices rebel, you need to take control:

Hierarchy and Orientation: The Family Tree That Matters

Before blaming the weights, check:

  1. Are the bones properly parented? (Parents and children in place)
  2. Are the orientations consistent? (No twisted bones like pretzels)
  3. Are the transformations clean? (Apply, apply, apply)

A poorly oriented bone can turn your character into a Lovecraftian nightmare. 🦑

Nuclear Reset: When Everything Else Fails

For extreme cases:

Redo the Skin Binding - Sometimes it's better to start from scratch than keep patching

Ghost Bone Hunt - Those hidden bones that keep influencing even if you can't see them

Backups - Because every digital artist needs a "regret" button

Remember: if after all this your model still deforms weirdly, you can always say it's an alien and sell it as an NFT. 👽 But with these tips, we hope you don't get to that... today. 😉
