How to Use
-
Write a prompt describing your scene or character (English or Chinese).
-
Set width and height .
-
Add one or more LoRAs:
- Paste LoRA path or URL (.safetensors).
- Adjust scale to tune blending intensity.
-
(Optional) Set a seed for reproducibility (
-1= random). -
Choose output format (JPEG / PNG / WEBP).
-
Generate → review → iterate with new LoRAs or parameters.
Pro tips for best quality
- Use portrait-focused LoRAs to enhance realism and consistency.
- Combine style + identity LoRAs for hybrid looks (e.g., fantasy portrait + cyberpunk mood).
- Keep scale moderate (0.7–1.0) for natural results.
- Fix seed to maintain identity when testing new LoRAs.
Reference
Note
- LoRAs from Civitai or Hugging Face are supported if exported as
.safetensors. - Model optimized for portrait, fashion, and cinematic generation—for landscapes or scenes, lower scale or combine with general LoRAs for balance.
