| | # luca-voss (LoRA) |
| |
|
| | **Trigger:** `[luca-voss]` [oai_citation:2‡config.yaml](sediment://file_00000000c168720a8bbd7cdbb17e97aa) |
| |
|
| | A character LoRA trained to generate a consistent male model identity ("luca-voss") with photorealistic/editorial portrait aesthetics. The model was trained on **Tongyi-MAI/Z-Image-Turbo** with a LoRA network configuration optimized for identity consistency and realistic skin detail.

| | ## How to use |
| |
|
| | ### Prompting |
| | Use the trigger token at the start of your prompt: |
| |
|
| | **Example (portrait/editorial):** |
| | `[luca-voss], 20-23-year-old man, dark brown strictly slicked-back hair, hazel-brown eyes, realistic skin texture, modern editorial portrait, photorealistic` |
| |
|
| | ### Style / scenario examples |
| | (These were used as sample prompts during training) [oai_citation:8‡config.yaml](sediment://file_00000000c168720a8bbd7cdbb17e97aa) |
| |
|
| | - Haute couture runway |
| | - White tie (tailcoat / frack) |
| | - Baywatch lifeguard vibe |
| | - 1950s greaser / James Dean inspired |
| | - Cyber-noir / Blade Runner inspired |
| | - Cowboy / western vibe |
| |
|
| | > Tip: For maximum identity stability, keep `[luca-voss]` at the beginning and add scene/outfit variations after. |

|
| | ## Recommended generation notes |
| |
|
| | - If you see overly glossy or wet-looking skin artifacts, reduce your detailer/upscale denoise and reinforce matte/anti-shine descriptors in negative prompts. |
| | - For stronger identity, prefer close-up / head-and-shoulders shots and consistent lighting across a series. |
| |
|
| | --- |
| |
|
| | ## Limitations |
| |
|
| | - As with most character LoRAs, extreme stylization or very low-resolution generations can reduce identity consistency. |
| | - Performance may vary across samplers and upscalers. |
