Overview

A nude version of my other macromastia LoRA.

Use the trigger early in your prompt. Further descriptions to the breasts position, framing and focus can help a lot to emphasize the effect (focus on her breasts, breasts take up a significant part of the frame, significant cleavage, or use camera angles and other related descriptors). Additional styles lying on her back and holding her breasts have also been trained into this model.

Sometimes it creates thicker or chubby bodies, for that you can include descriptors like slim or skinny or use negative prompt if possible.

Using the LoRA without any trigger can still increase nude breast shape and nipples, especially the texture and veins.

Values over 1.0 may produce heavy artifacts. Decrease strength if you encounter artifacts.

For more have a look at the example images/videos.

FLUX.2 [klein] 9B - V1

I recommend using FLUX.2 [klein] 9B distilled for inference.

This is a POC. Anatomy can get really messed up and multiple tries may be required. Experiment with seed and strength, as well as detailed descriptions. A higher quality update coming soon.

Training model: FLUX.2 [klein] Base 9B

LoRA strength: 0.3-1.0

Sampler: euler / DPM++ 2M / DPM++ 3M SDE

Steps: 4+

CFG: 1.0 (up to 5.0 with base model)

A POV image of a completely naked woman with gigantic breasts lying on a bed. The woman is nude and uncovered, looking at the camera from a slightly low angle, moaning intimately. Her belly button visible. Warm cozy bedroom setting.

ZIB - V1

This model may also work with Z Image Turbo on higher strengths (1.0-2.0).

After using the trigger macromastia, use additional triggers large, huge and gigantic to control the size further.

Experimenting with negative prompts and strength can be very rewarding.

Training model: Z Image

LoRA strength: 0.3-1.0 (up to 2.0 on Turbo)

Sampler: euler / res_multistep / DPM++ 3M SDE

Steps: 40+ (8+ on Turbo)

CFG: 3.0-5.0 (1.0 on Turbo)

A photo of a naked woman with macromastia sitting in the bathtub. She has absolutely gigantic breasts and full lips. Water in the tub, her body partially submerged in water, bubble bath. Wet hair and shiny skin.

ZIT - V1

Not compatible with Z Image Base.

Training model: Z Image De-Turbo

LoRA strength: 0.3-1.0

Sampler: euler / res_multistep / DPM++ 3M SDE

Steps: 8+

CFG: 1.0

Prompt example:

A photo of a topless woman with gigantic breasts is lying on her back in bed. She is taking a selfie with her arms extended towards the camera, her breasts covering part of her face and a significant part her torso. Her breasts are extremely round and massive. Focus on her breasts.
