R+ images will be hidden from the gallery. LoRA model trained with Flux, Z Image Turbo and Krea 2.Putting a Like to the V67 models is worth more than giving me Buzz (yellow/green).<hr /><h3 id="trigger-words">Trigger Words</h3>(use any combination) (heterochromia:1.5), different colored eyes, two eye colors, mismatched irises, left eye right eye different, dual eye colors, iris heterochromia, contrasting eyes, odd eyes, bicolor eyes<hr /><h3 id="overview">Overview</h3>V67 Heterochromia is a specialized LoRA designed to generate stunning portraits where the eyes are the focal point – across women, men, animals, and aliens. It excels at producing realistic, artistic, and fantastical heterochromia (complete, sectoral, or central) with precise color separation, natural iris textures, and cohesive lighting.Originally trained for Z-Image Turbo, it is now also compatible with FLUX (let me know how it works for you!). Whether you need human character art, animal close‑ups, sci‑fi aliens with mismatched eyes, or simply want to give any subject a unique and captivating trait, this LoRA delivers consistent, high‑quality results across all four categories.<hr /><h3 id="character-features-(by-category)">Character Features (by category)</h3>CategoryKey TraitsWomenComplete, sectoral, or central heterochromia; natural or fantasy colors; works with any ethnicity, hair color, and style (portrait, beauty, editorial).MenSame realistic or stylized heterochromia; rugged, refined, or fantasy looks; strong gaze and masculine features preserved.AnimalsMammals (cats, dogs, wolves, horses) with natural heterochromia (amber+blue, green+yellow); fur texture, realistic eyes, species‑accurate anatomy.AliensUnnatural color pairs (violet+gold, crimson+cyan); slit pupils, glowing effects, bioluminescent sclera; sci‑fi or fantasy alien designs.All subjects maintain:<ul><li>Realistic iris texture – fine details, limbal ring, light refraction</li><li>Balanced lighting – colors react naturally to the environment</li><li>Expressive gaze – emotions and personality enhanced by the unique eye contrast</li></ul><hr /><h3 id="style-and-aesthetic">Style &amp; Aesthetic</h3><ul><li>Anatomical accuracy – Proper sclera, cornea reflections, and skin/fur integration.</li><li>Versatile genres – From subtle real‑life portraits to bold fantasy, cyberpunk, sci‑fi, and animal photography.</li><li>Lighting awareness – Each eye color reacts independently to light sources, adding depth and realism.</li><li>Cross‑category consistency – Works seamlessly for humans, animals, and aliens without losing identity.</li></ul><hr /><h3 id="sample-prompts-(tested)">Sample Prompts (tested)</h3>👩 Women – Natural &amp;

reduce LoRA weight or adjust prompt. ⚠️ Group scenes – Multiple characters with heterochromia may cause occasional cross‑contamination; best for one or two subjects. ⚠️ Sectoral heterochromia – Requires careful prompting (e.g., “sectoral heterochromia, brown patch in blue eye”) for consistent results. ⚠️ Animal variety – Primarily trained on mammals; reptiles, birds, or exotic animals may need additional prompt refinement. ⚠️ Alien designs – Very complex or multi‑eye alien designs may require combining with other LoRAs for full effect.<hr /><h3 id="recommended-settings">Recommended Settings</h3>For Z-Image TurboParameterRecommended ValueLoRA Weight0.7 – 1.0Guidance Scale3.5 – 5.0Steps4 – 8 (Turbo optimized)Resolution1024×1024 (native)Tip: Start with 4 steps and LoRA weight 0.8. Increase to 8 steps if more detail is needed. The LoRA responds well to Turbo’s distillation.For FLUX (beta)Start with the same weight range (0.7–1.0) and use FLUX’s standard step settings (20–30 steps). Please let me know your results – feedback helps improve FLUX compatibility!<hr /><h3 id="trigger-words-and-prompt-structure">Trigger Words &amp; Prompt Structure</h3>Activate the LoRA using any combination of trigger words. The model responds to both keywords and natural language.Example prompt structure: <code>close-up portrait of a [woman/man/animal/alien] with heterochromia, left eye [color], right eye [color], [lighting], [style], V67 Heterochromia</code>For best results:<ul><li>Specify each eye color separately (e.g., “left eye X, right eye Y”).</li><li>Include lighting conditions to enhance color separation.</li><li>Use portrait framing to keep eyes prominent.</li></ul><hr /><h3 id="example-variations-to-try">Example Variations to Try</h3><ul><li>Warm vs. Cool Contrast (Woman) <code>close-up, heterochromia, left eye warm amber, right eye cool arctic blue, dramatic lighting, half face in shadow, V67 Heterochromia</code></li><li>Masculine Gaze (Man) <code>portrait of a man with heterochromia, one eye dark brown, one eye steel blue, rugged features, black and white with selective color, V67 Heterochromia</code></li><li>Sectoral Heterochromia (Cat) <code>heterochromia cat, sectoral heterochromia, blue eye with a brown wedge, realistic iris texture, natural daylight, macro shot, V67 Heterochromia</code></li><li>Glowing Fantasy Eyes (Alien) <code>alien with heterochromia, one eye gold with slit pupil, one eye silver with ethereal glow, alien jungle background, bioluminescent plants, V67 Heterochromia</code></li><li>Sci‑Fi Soldier (Man) <code>cybernetic soldier, heterochromia, left eye biological hazel, right eye cybernetic red with targeting reticle, gritty dystopian background, V67 Heterochromia</code></li></ul><hr /><h3 id="training-details">Training Details</h3><ul><li>Dataset: 300+ curated images covering women, men, animals (cats, dogs, wolves, horses), and aliens.</li><li>Base Model: Z-Image Turbo (FLUX compatibility added post-training).</li><li>Training Method: LoRA with rank 16, alpha 16, learning rate 1e-4, adapted for Turbo’s distillation architecture.</li><li>Epochs: 15</li><li>Resolution: 1024×1024</li><li>Captioning: Detailed natural language captions describing category, eye colors, type of heterochromia, lighting, and composition.</li></ul><hr /><h3 id="credits-and-notes">Credits &amp; Notes</h3>This LoRA celebrates the natural beauty and intrigue of heterochromia across all forms of life – and beyond. Whether you’re designing human heroes, faithful animal companions, or extraterrestrial beings, V67 Heterochromia will make their eyes unforgettable.Tagger’s Note: For best results with Z-Image Turbo, keep steps low (4–8). For FLUX, use standard settings. The model is lightweight and can be combined with other LoRAs (e.g., for style, ethnicity, or specific animal breeds) with minimal interference.Share your creations and tag them with #V67Heterochromia.Two colors, one story – for everyone. 🧬👁️👁️
