🌿 Ivy Generator Controller for Blender

-Ivy Generator Controller- is a custom Blender add-on that lets you quickly grow procedural ivy on any object using Geometry Nodes and instancing. Ideal for creating nature scenes, fantasy environments, overgrown ruins, and more — all with full control over materials and growth behavior.

Designed for Blender artists who want fast, customizable greenery — without the pain of manual ivy modeling.

✨ Features

• 🌱 Procedural ivy growth using Geometry Nodes
• 🧩 Supports multiple independent ivy controllers
• 🎛️ Custom UI panel for material control (color, roughness, translucency, etc.)
• 🎨 Unique materials per controller instance
• 🗂️ Automatic instancing with unique collections per controller
• 🧠 Smart naming (Ivy Controller, IVY_Instance_Collection.001, etc.)
• 🧼 Clean structure and fully undoable
• 💡 Ready for integration into modular environments or asset libraries

🧰 Requirements

• Blender 4.5+ (tested in 4.5)
• No third-party dependencies
• Works with both Cycles and Eevee

🔧 Installation

1. Download the ivy_generator_controller.zip from Releases or clone this repo.
2. In Blender, go to Edit > Preferences > Add-ons
3. Click Install... and choose the zip file
4. Enable Ivy Generator in the add-on list
5. Done! The tool appears in the 3D View > Sidebar > Ivy Generator tab

🚀 Usage

1. Select any mesh object in your scene
2. In the Sidebar (press N), go to the Ivy Generator tab
3. Click 🌿 Apply Ivy to Selected Object
4. A new object named Ivy Controller appears — this drives the ivy growth
5. Customize the ivy material under the BagaLeaf Material panel

🎛️ Material Controls

Each Ivy Controller generates instanced leaves with a unique material copy.

You can:

• Adjust color, roughness, translucency, and alpha
• Control parameters via the embedded "BagaLeaf" Node Group
• Apply different settings to each controller separately

🧪 Pro Tips

• Use multiple Ivy Controllers on different surfaces (rocks, trees, buildings)
• Animate the ivy by modifying node group parameters or blending modifiers
• Replace the instance collection with your own custom leaf models
• Optimize materials by linking shaders between controllers, if needed

📣 Known Limitations

• Only one Base Collection is currently used for all original source objects
• All ivy controllers must be generated via the add-on panel (not manually duplicated)

🙏 Credits

• Developed by [HyperSpace Academy]
• Geometry Nodes inspired by Blender community experiments
• Material shading system: fully procedural, powered by the BagaLeaf node group
