<h1 id="overview">Overview</h1>A nude version of my <a target="_blank" rel="ugc" href="https://civarchive.com/models/2294035">other</a> macromastia LoRA.The model is pretty straight forward. Use the trigger early in your prompt. Further descriptions to the breasts position, framing and focus can help a lot to emphasize the effect.Sometimes it creates thicker or chubby bodies, for that you can include descriptors like <code>slim</code> or <code>skinny</code> or use negative prompts.Values over <code>1.0</code> may produce heavy artifacts. Decrease strength if you encounter artifacts. Most samples use a strength of <code>0.9</code>.For more, have a look at the example images/videos.<h3 id="ltxv-2.3-(sulphur-2)-v1">LTXV 2.3 (Sulphur 2) - V1</h3>Coming in July...<h2 id="krea-2-turbo-v1">Krea 2 Turbo - V1</h2>Use the trigger <code>mcrmst</code> and describe the breast/cleavage in some detail.

Things break and body horror may occur.Trained on bounding boxes and JSON, but can be used without JSON structure prompts.
