Explaining Negative Prompts for Hands, Arms, Legs, and Feet

Negative Prompts for Hands, Arms, Legs, and Feet

Using Correct Danbooru Digit-Based Tags

When working with Illustrious models, anatomy errors in hands and feet are almost always digit-count and joint-structure problems.For Danbooru-based models, the AI does not separate fingers and toes in logic. They are treated as digits.

Because of this, digit-based negatives are the correct and reliable approach. _ Why Digit-Based Negatives Matter

Danbooru tagging treats: ~ fingers ~ toes

as the same concept: digits.

If you rely only on finger-specific wording, the model may: ~ still generate wrong toes ~ ignore foot anatomy issues ~ partially fix hands but not feet

Digit-based negatives apply to: ~ hands ~ feet ~ fingers ~ toes at the same time. __ Core Digit-Control Negatives (Danbooru-Standard)

These are the most important anatomy negatives and should be considered baseline for most full-body or visible-limb generations.

Use together: ~ extradigits ~ missingdigits ~ fuseddigits ~ malformeddigits ~ toomanydigits ~ toofewdigits

These control: ~ extra fingers ~ missing fingers ~ extra toes ~ missing toes ~ merged or melted digits

This is the correct Danbooru-safe method. __ Controlling Specific Digit Count Errors If you are seeing: ~ 3 digits ~ 4 digits ~ 6 digits

Add explicit digit-count negatives: ~ threedigits ~ fourdigits ~ six_digits

These directly tell the model that incorrect digit counts are forbidden, regardless of whether they appear on hands or feet.

This is why fixing hands often fixes feet automatically. __ Preventing Deformed Hands and Feet

Digit control alone is not always enough. You also need to block shape collapse and structure loss.

Use: ~ malformedhands ~ malformedfeet ~ deformedhands ~ deformedfeet

These prevent: ~ melted hands ~ blob-like feet ~ loss of joint definition __ Fixing Arms and Legs (Limbs and Joints)

Arms and legs usually break due to joint confusion or overlap.

Use: ~ badanatomy ~ malformedlimbs ~ extralimbs ~ missinglimbs ~ dislocated_joints

These apply to: ~ arms ~ legs ~ hands ~ feet

and help stabilize full-body poses. __ When Hands or Feet Look Blurry or Unfinished

If limbs look: ~ soft ~ blurry ~ incomplete

Add: ~ blurryhands ~ blurryfeet ~ poorlydrawnhands ~ poorlydrawnfeet

These block low-detail fallback behavior. __ Example: Clean Danbooru Anatomy Negative Block

This is a safe, generator-friendly anatomy negative set that works across most Illustrious models: ~ badanatomy ~ extradigits ~ missingdigits ~ fuseddigits ~ malformeddigits ~ toomanydigits ~ toofewdigits ~ threedigits ~ fourdigits ~ sixdigits ~ malformedhands ~ malformedfeet ~ extralimbs ~ missinglimbs ~ dislocated_joints

This controls: ~ hands ~ feet~ fingers ~ toes ~ arms ~ legs

without over-restricting the model. __ Important Beginner Warning

Do not stack every anatomy negative you find.

Too many digit and limb negatives can cause: ~ stiff poses ~ hidden hands ~ cropped feet ~ awkward framing

If the model starts avoiding hands or feet entirely, remove some negatives.

Negatives should guide anatomy, not scare the AI away from drawing it. __ Final Rule for Body Anatomy (Danbooru)

If digits are wrong: ~ use digit-based negatives

If limbs are distorted: ~ add limb and joint negatives

If detail disappears: ~ remove negatives

Always adjust slowly and test one change at a time. _

One Final Note

Before judging a model, always check your prompt first.
