# 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** |
