# 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. [oai_citation:3‡config.yaml](sediment://file_00000000c168720a8bbd7cdbb17e97aa)

## 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.
