# Flux LoRA Model Cascade

**Category:** ⚡FluxReactor / Model Loader  
**Node Name:** `Flux_LoRA_Model_Cas`  
**Author:** `solongeran_54`

---

## 🧩 Purpose  
The `Flux LoRA Model Cascade` node introduces a **new intermediate workflow layer** between base model loading and LoRA injection. It enables structured and modular application of one or more LoRA files—including automatically chained parts (`lora2.safetensors`, `lora3.safetensors`, etc.)—**without requiring merge operations.**

---

## ✨ Key Features  
- **⚙️ Cascade Loader**  
  Automatically detects and loads chained LoRA files (`LoRA`, `LoRA2`, `LoRA3`, etc.) if they exist in the same folder.

- **🎛️ Independent Weight Control**  
  Apply up to three LoRA modules simultaneously, each with an individual strength slider.

- **🚫 No Merge Required**  
  LoRAs are applied in-place without altering the base model or writing new files—preserving performance and flexibility.

- **🔀 Modular Micro-LoRA Design**  
  Ideal for **small, theme-based LoRA modules** ("mini flux models") used for specific workflows, styles, or custom experiments.

- **🧪 Workflow Integrator**  
  Designed as a mid-point node—plug it in between your base model loader and any prompt-related or inference nodes.

- **🛡️ Safety Mechanism**  
  Includes a lightweight runtime integrity check to prevent unexpected tampering or misuse.

## 🔗 Example Use Case
```mermaid
graph TD;
    A[Checkpoint Loader] --> B[Flux LoRA Model Cascade];
    B --> C[Prompt Conditioning];
    C --> D[KSampler / Output];
```

This node does **not** override the base model. It *layers* selected LoRA influences cleanly into your generation pipeline.

---

## 🧠 Tips for Advanced Users  
- Combine lightweight LoRA parts for **granular style control**.  
- Use low strength values for **subtle, non-invasive influences**.  
- Use as a **testing tool** for LoRA development (e.g. loading part2, part3 automatically).

## 📁 LoRA Folder Structure Example
```
/loras/
 ├── comic_filter.safetensors
 ├── comic_filter2.safetensors
 ├── comic_filter3.safetensors
 └── glassy_touch.safetensors
```

If `comic_filter` is selected, all its numbered parts will be applied in order.

---

## 🔒 Integrity & Security
The node includes an internal signature check (`do_nothing()` function) to ensure that it has not been altered. This is a simple runtime self-check designed to maintain operational trust and prevent execution under tampered conditions.

---

## 🧬 Outputs  
- ✅ Updated `MODEL` and `CLIP` objects  
- 📝 Log string with applied LoRAs and strengths

---

## ✅ Perfect for:
- Dynamic workflows without model merging  
- Testing new LoRA fragments quickly  
- Creating custom model themes using small LoRA modules  
- Keeping your generation stack **clean and modular**
