+
+# apti_tex Tool
+
+A lightweight GUI utility for exporting and importing `*.apti_tex` texture files.  
+The tool converts `*.apti_tex` files into `*.DDS` (BC3/DXT5) for editing in applications such as GIMP, and then repacks edited DDS files back into the apti_tex format.
+
+## Features
+- Export `.apti_tex` files to `.DDS`
+- Supports editing DDS files in BC3/DXT5 format
+- Import edited `.DDS` files back into `.apti_tex`
+- Simple Tkinter-based interface
+- Error and status notifications via message boxes
+
+## How It Works
+- **Export:** Reads the custom header, extracts raw texture data, and builds a valid DDS output file.
+- **Import:** Validates the DDS header, rebuilds the apti_tex structure, and writes a new `.apti_tex_NEW` file.
+
+## Requirements
+- Python 3.x  
+- `binary-reader`  
+- `tkinter`  
+- `opencv-python`  
+
+## Usage
+Run the main script:
+**python apti_texTool.py**
+
+
+Then use the GUI buttons to export or import textures.
