## Installation

These workflows use models downloaded via `artifact_civitai_download.sh`:

```bash
# Models are already downloaded to /workspace/models/civitai/
# and symlinked to /workspace/ComfyUI/models/checkpoints/

# Verify models are available:
ls -lh /workspace/ComfyUI/models/checkpoints/lustify*
ls -lh /workspace/ComfyUI/models/checkpoints/*pony*
ls -lh /workspace/ComfyUI/models/checkpoints/realvisx*
```

## Usage

### Via ComfyUI API:

```bash
# Load workflow
curl -X POST http://localhost:8188/api/prompt \
  -H "Content-Type: application/json" \
  -d @lustify-realistic-t2i-production-v1.json

# Modify prompt and generate
curl -X POST http://localhost:8188/api/prompt \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": {
      "2": {
        "inputs": {
          "text": "Your custom NSFW prompt here"
        }
      }
    }
  }'
```

### Via ComfyUI UI:

1. Open ComfyUI at `http://localhost:8188`
2. Click "Load" and select workflow file
3. Modify prompt in the "API Positive Prompt" node
4. Click "Queue Prompt" to generate

## Model Comparison

| Model | Type | Speed | Quality | Best For | Prompt Style |
|-------|------|-------|---------|----------|--------------|
| LUSTIFY v7 | Photoreal | Medium (30 steps) | Excellent | Women, realistic scenes | Natural language |
| Pony Diffusion v6 | Anime/Furry | Medium (35 steps) | Excellent | Anime, cartoon, furry | Danbooru tags |
| RealVisXL Lightning | Photoreal | Very Fast (4-6 steps) | Excellent | Quick realistic generations | Natural language |

## Tips

### For LUSTIFY:
- Use detailed prompts describing scene, lighting, quality
- Avoid abstract/artistic terms
- Include photography keywords: "professional photography", "8k", "detailed"
- CFG 4-7 range works best

### For Pony Diffusion:
- Danbooru tags work very well (recommended over natural language)
- Use tag format: `1girl, solo, breasts, smile, looking_at_viewer`
- Mix safe/questionable/explicit content naturally
- Can do anime, cartoon, and furry styles
- Supports wide range of artistic styles
- CFG 7-8.5 range works best

### For RealVisXL Lightning:
- Keep prompts concise for best results
- Use lower CFG (1-2) for Lightning models
- 4-6 steps is optimal balance
- Great for batch generation

## Advanced Usage

### Adding LoRAs:
Use the `../text-to-image/lora-fusion-t2i-production-v1.json` workflow for multi-LoRA stacking support.

**How to use with NSFW models:**
1. Load the LoRA fusion workflow
2. Change checkpoint (node 1) to your NSFW model (LUSTIFY, Pony, RealVisXL)
3. Stack up to 3 LoRAs with adjustable weights:
   - LoRA 1 (Primary): 0.7-1.0 strength
   - LoRA 2 (Secondary): 0.4-0.7 strength
   - LoRA 3 (Accent): 0.2-0.5 strength
4. Common use cases:
   - Detail enhancer + skin texture + lighting style
   - Character LoRA + pose enhancer + background style
   - Primary art style + secondary blend + color grading

### Upscaling:
Use `nsfw-ultimate-upscale-production-v1.json` for professional 2x upscaling with LUSTIFY checkpoint.

**Workflow:**
1. Generate image with any NSFW T2I workflow (LUSTIFY, Pony, RealVisXL)
2. Load the generated image into Ultimate SD Upscale workflow
3. Use denoise 0.2-0.3 for subtle enhancement
4. Match enhancement prompt to original generation prompt
5. Output: 2048x2048 high-quality upscaled image

### Style Transfer:
Use IP-Adapter workflows in `../image-to-image/` directory to combine with style references.

## Notes

- All workflows follow production naming standards
- VRAM requirement: ~12GB per SDXL model
- Can run one NSFW model at a time on 24GB GPU
- Models automatically use BakedVAE when available
- Face enhancement can be added via Impact-Pack nodes
