Example Output## Usage Examples


Input: "a woman in a garden"```

Platform: fluxInput: "A cat playing piano"

Genre: cinematicPreset: Cinematic

Length: mediumTier: Auto (detects "Enhanced")



Output: "Cinematic medium shot portrait of an elegant woman in a lush garden Output: "A fluffy orange tabby cat sits at a polished black grand piano in a warmly lit living room. The cat's paws press down on the ivory keys with surprising dexterity. Soft afternoon light streams through a nearby window, creating edge lighting on the cat's fur. Medium close-up shot, eye-level angle. The camera slowly pushes in as the cat continues to play. Warm color palette, soft lighting, clean single shot."

Input: "The woman turns and walks toward the camera"

---Mode: Image-to-Video

Preset: Noir

📚 DocumentationPositive Keywords: myLoRA_trigger, detailed_face

Tier: Advanced

Comprehensive guides in docs/:

Output: "The woman slowly turns her head, edge lighting creating dramatic shadows across her face, myLoRA_trigger, detailed_face. She begins walking directly toward the camera with deliberate, purposeful steps. Her silhouette is backlit by a single streetlight, creating a strong rim light effect. The camera remains static as she approaches, her features gradually emerging from shadow. High contrast lighting, desaturated colors, low angle shot. The scene has a tense, mysterious atmosphere."

LLM Connection- Detailed breakdown

Check server is running (LM Studio "Running" status)- Metadata (preset, tier, model, temperature)
Verify endpoint URL matches- Original input
Model name exact match (case-sensitive)

Troubleshooting

Output Quality

Adjust prompt_length for target size### "Cannot connect to LM Studio/Ollama"
Verify genre_style matches mood- Ensure LM Studio or Ollama is running
Update to v1.6.1+ for bug fixes- Check the API endpoint URL
Verify the model is loaded

Node Not Appearing

Restart ComfyUI after installation### "Request timed out"
Check "Eric Prompt Enhancers" category- LLM might be slow on complex prompts
Run pip install -r requirements.txt- Try lowering the tier
Reduce temperature

---- Use a smaller/faster model
