BustMorph Slider

SMALL ↔ LARGE — Breast Size Control

One LoRA. Full Control Over Breast Volume.

BustMorph Slider is a bidirectional body proportion slider designed to adjust breast size using positive or negative LoRA weights.

Whether you want a subtle reduction, a natural increase or an exaggerated silhouette, BustMorph provides flexible control without requiring complicated prompts.

How It Works

Negative Weights — SMALL BUST

• Reduces breast volume

• Creates smaller bust proportions

• Works with fitted clothing and unclothed anatomical studies

• Strong negative weights can produce a nearly flat chest

Positive Weights — LARGE BUST

• Increases breast volume

• Allows gradual size adjustments

• Influences clothing fit and fabric contours

• Higher strengths produce significantly larger proportions

Tested Results

Initial comparisons demonstrate gradual control across negative and positive weights.

The slider has been tested with fitted dresses, cotton T-shirts and unclothed anatomical reference portraits.

The most balanced positive results were observed around +0.25 to +0.75.

Stronger positive weights may produce exaggerated proportions, and the slider can also influence clothing contours and minor aspects of the overall composition.

Results may vary depending on the checkpoint, prompt, seed and subject.

Recommended Workflow

1. Load your compatible Krea2 Turbo checkpoint.

2. Add BustMorph Slider to the generation.

3. Start at -1.0, +0.5 or +1.0.

4. Adjust the LoRA strength gradually.

5. For controlled comparisons, keep the same seed, steps, guidance and resolution.

Important Notes

• Extreme weights may produce unrealistic anatomy.

• Positive and negative strengths are not necessarily symmetrical.

• Results can vary across clothing types, body shapes and camera angles.

• Use moderate weights when realistic proportions are important.

• Compatibility with additional checkpoints should be verified individually.
