## LoRA Configuration (ComfyUI)

**⚠️ IMPORTANT: LoRA ไม่มี Trigger Words**

Qwen Image Edit LoRAs ไม่ต้องใช้ trigger words พิเศษ เขียน prompt เป็นภาษาธรรมชาติได้เลย
ระบบจะ activate LoRA อัตโนมัติตามที่เปิดใช้งาน

### Available LoRAs

| LoRA | Purpose | When to Enable |
|------|---------|----------------|
| **Multiple-angles** | เปลี่ยนมุมกล้อง | Prompt เกี่ยวกับ camera angle (low/high angle, side view, etc.) |
| **consistence_edit** | รักษา consistency | ต้องการให้ผลลัพธ์คงเดิมมากที่สุด |
| **bfs_head_swap** | สลับหัว/หน้า | ใช้ 2 รูป - เอาหน้าจากรูป 1 ไปใส่รูป 2 |
| **clothes_tryon** | เปลี่ยนเสื้อผ้า | ใช้ 2 รูป - เอาเสื้อผ้าจากรูป 1 ไปใส่คนในรูป 2 |
| **Lightning-4steps** | เร่งความเร็ว (4 steps) | **Default ON** - ใช้เสมอเพื่อความเร็ว |
| **Lightning-8steps** | เร่งความเร็ว (8 steps) | ถ้า 4 steps ไม่ work ค่อยลอง 8 |

### Default Settings

- **เปิด:** Lightning-4steps เท่านั้น
- **ปิด:** LoRA อื่นๆ ทั้งหมด (เปิดตาม task)

### LoRA Selection by Task

| Task | LoRAs to Enable | Steps |
|------|-----------------|-------|
| **Basic edit** (แสง, สี, พื้นหลัง) | (none, ใช้ default) | 4 |
| **Camera angle change** | Multiple-angles | 4 |
| **Head/face swap** | bfs_head_swap | 4 |
| **Clothes change** | clothes_tryon | 4 |
| **High consistency** | consistence_edit | 4 |
| **Quality mode** | ปิด Lightning ทั้งคู่ | 20 |

### Speed vs Quality

| Mode | Lightning LoRA | Steps | Time | Use Case |
|------|----------------|-------|------|----------|
| **Fast** | 4-steps ON | 4 | ~10s | Iteration, testing |
| **Medium** | 8-steps ON | 8 | ~20s | ถ้า 4 steps ไม่ดีพอ |
| **Quality** | ทั้งคู่ OFF | 20 | ~50s | Final output |

### Multi-Image Editing

Qwen Image Edit รองรับ **1-3 รูป** สำหรับ reference:

| Images | Use Case | Example Prompt |
|--------|----------|----------------|
| **1 รูป** | Edit รูปเดียว | "Turn to side profile view" |
| **2 รูป** | Combine/swap elements | "Use face from image 1, pose from image 2" |
| **3 รูป** | Complex composition | "Combine elements from all three images" |

### Reference-Based Editing Best Practices

**⚠️ CRITICAL: อย่าบรรยายใบหน้าเมื่อใช้ reference image**

เมื่อใช้รูป reference สำหรับใบหน้า/ตัวคน:
- ❌ **ห้าม:** "A woman with curly hair, round face, wearing glasses..."
- ✅ **ถูกต้อง:** "Use the face from image 1" หรือ "Keep the person's appearance"

**เหตุผล:** Dual-path encoding ของ Qwen จะดึง visual features จากรูปโดยตรง การบรรยายซ้ำอาจทำให้เกิด conflict

**Pattern ที่แนะนำ:**
```
[Action/Change] + [Reference to which image] + [What to preserve]
```

**ตัวอย่าง:**
| Task | Prompt |
|------|--------|
| Face swap | "Replace face with the person from image 1. Keep pose and clothing." |
| Style transfer | "Apply the art style from image 2. Keep the subject unchanged." |
| Outfit change | "Dress in the outfit from image 2. Keep face and pose." |
| Pose transfer | "Adopt the pose from image 2. Keep the person's identity." |

### Prompt Tips for LoRA Tasks

**Camera Angle (Multiple-angles):**
```
Turn the camera to a low-angle view, looking up at the subject.
Keep appearance and clothing unchanged.
```

**Head Swap (bfs_head_swap):**

มี recommended prefix `h34d_sw4p:` ที่อาจช่วยให้ผลลัพธ์ดีขึ้น:

```
h34d_sw4p: replace the head of Picture 1 by the head from Picture 2,
strictly preserving the identity, facial features (eyes, nose, mouth),
and skin texture of Picture 2.
```

หรือแบบ simple (focus face only):
```
face swap face from Image 1 to Image 2. swap only the face and not the hair.
```

**Tips:**
- Image 1 = face source, Image 2 = body/pose
- High-quality input ไม่มี compression artifacts จะได้ผลดีกว่า

**Clothes Change (clothes_tryon):**
```
Dress the person in image 1 with the outfit from image 2.
Keep the original pose and background.
```

## Tips

1. **Prompt length:** 1-3 sentences optimal, paragraph OK
2. **Text in quotes:** For on-image text, use quotes and specify font
3. **Seed for iteration:** Lock seed to iterate on details
4. **CFG with Lightning:** ต้องใช้ CFG=1.0 เท่านั้น (fixed)
5. **CFG without Lightning:** 2.5-4.0 แนะนำ
6. **Lightning LoRA:** 4-step default, เปิด LoRA อื่นตาม task
7. **Start simple:** ลอง default ก่อน ค่อยเปิด LoRA เพิ่ม
8. **Quality for final:** ปิด Lightning + 20-40 steps สำหรับ final output
9. **Reference images:** อย่าบรรยายใบหน้าซ้ำ ให้ระบบดึงจากรูป
