🧪 One-Click Normal Map Generator – Documentation


🔧 Overview

The One-Click Normal Map Generator allows you to quickly and easily convert grayscale mask images into high-quality normal maps inside Blender. The addon provides a clean, interactive panel to import your image, tweak settings, and generate normal maps in seconds.

📦 Sections & Functions

✅ Dependency Installation

  • Install Dependencies

    (For Windows Users Please Run Blender as Administrator on the first installation.)

    Automatically installs all required Python modules (numpy, opencv-python, Pillow, requests) into Blender's environment.

  • Check Dependency Installation
    Verifies whether all necessary modules are installed. Displays a confirmation message if successful.

🖼 Import Image

  • Import Image
    Opens a file browser to choose a grayscale image (e.g., height map, roughness, logo, etc.).

  • Path
    Displays the selected file path.

  • Preview
    Shows a live thumbnail of the imported image.

⚙️ Settings

  • Radius
    Controls the edge blur radius for slope simulation. Larger values create smoother transitions.

  • Strength
    Adjusts the intensity of the resulting normal map.

🧭 Normal Map Type

  • NormalMapType.DX (DirectX)
    Y+ axis normal map style (used in many engines like Unreal Engine).

  • NormalMapType.GL (OpenGL)
    Y- axis normal map style (used in engines like Unity or Blender default).

🔁 Options

  • Invert Mask
    Inverts black/white values before processing.

  • Disable Blurring
    Skips the slope generation blur and uses the raw mask as a height map.

🧪 Generate Normal Map

  • Button: Generate Normal Map
    Processes the image and creates a normal map based on your current settings. Saves the result in the same directory as the source image with a _normal.png suffix.

  • Output Path
    Displays where the new normal map is saved.

  • Preview
    Shows a live thumbnail of the generated normal map.

📂 Post Processing

  • Open Image
    Opens the generated normal map in Blender’s image editor.

  • Import Image Blender
    Loads the normal map directly into Blender’s image datablock for use in materials or texture slots.

📝 Notes

  • This addon runs fully in the background and refreshes the UI automatically after generation.

  • Ideal for logos, decals, masks, and PBR workflows where quick depth simulation is needed.
