A comprehensive workflow optimization toolkit for ComfyUI, providing essential nodes for model management, sampling control, and workflow enhancement with professional-grade reliability.

🚀 Features

Model Management

💀Prepack Model DualCLIP - Load models with dual CLIP encoders
💀Prepack Model SingleCLIP - Load models with single CLIP encoder
💀Prepack Loras - Apply up to 3 LoRA adapters with text document integration
💀Prepack Loras and MSSD3 - LoRA management with MSSD3 support

Sampling Control

💀Prepack Ksampler - Enhanced KSampler with optimized parameters
💀Prepack Ksampler Advanced - Advanced sampling control with additional options
💀Prepack Seed - Smart seed management with random generation and history tracking

Workflow Management

💀Prepack SetPipe - Set and store workflow pipeline states (now includes LoRA path support)
💀Prepack GetPipe - Retrieve and use stored pipeline states (now includes LoRA path output)

Logic Operations

💀Prepack Logic Int - Integer logic operations and comparisons
💀Prepack Logic String - String logic operations and manipulations

Integer Operations

💀Prepack Int Combine - Combine up to 4 integers into a string with selectable separator
💀Prepack Int Split - Split a string into up to 4 integers using selectable separator

Math Operations

💀Prepack Calculator - Evaluate mathematical expressions with variables a, b, c, d. Supports custom formulas like (a*c)+d/2. Outputs both integer and float results

Type Conversion

💀Prepack Number Type Converter - Convert between string, int, and float types. Accepts any of these types and outputs all three simultaneously

File Management

💀Save By File Name - Smart file saving with format preservation and custom naming. Supports images (WebP, JPEG, PNG, GIF), videos (MP4, AVI), and text files with automatic format detection

Workflow Tools

💀Export Workflow as PNG - Export complete workflow as PNG image with embedded workflow data or image only. Accessible via right-click canvas menu

📦 Installation

Method 1: ComfyUI Manager (Recommended)

Open ComfyUI Manager
Search for "Prepack"
Click Install
Restart ComfyUI

Method 2: Manual Installation

Navigate to your ComfyUI custom_nodes directory:
```
cd ComfyUI/custom_nodes/
```

Clone this repository:

git clone https://github.com/S4MUEL-404/ComfyUI-Prepack.git

Install dependencies (minimal requirements):

pip install -r ComfyUI-Prepack/requirements.txt

Restart ComfyUI

🔧 Dependencies

This package has minimal dependencies and uses built-in ComfyUI functionality:

PyTorch - Core tensor operations (usually already available)
NumPy - Numerical computations (usually already available)

All dependencies are typically already available in standard ComfyUI installations.

📖 Usage

Find Nodes: All Prepack nodes are prefixed with 💀 in the ComfyUI node browser
Categories: Look under "💀Prepack" category
Professional Quality: All nodes include comprehensive error handling
Smart Features: Advanced UI controls with JavaScript extensions
