Procedural Terrain Generator & Material Blending Tool

This 2-in-1 Blender add-on lets you generate customizable procedural terrain and blend multiple materials based on elevation. Create natural-looking landscapes in seconds, preview them with color zones, then apply any materials and combine them into a single shader. Simple, fast, and flexible—perfect for asset creation and exporting.

Create stunning, customizable terrain directly inside Blender with the Procedural Terrain Generator Add-on. Design natural landscapes using noise-based geometry and assign layered materials based on height zones — all in real-time, with intuitive sliders.

This add-on is perfect for game developers, environment artists, and 3D creators who need a fast and flexible terrain creation workflow inside Blender.

🎯 Features:

• Generate procedural terrain geometry using advanced noise functions
• Real-time preview with live adjustment sliders (zoom, height, seed, etc.)
• Assign materials or textures to terrain based on height zones
• Control texture blending using top and bottom weights for maximum flexibility
• One-click material application for multi-textured terrain
• Simple UI integration in the sidebar (N-panel)
• Fully compatible with Blender’s shading and export tools
  

Usage Instructions:

1. Add Terrain:

Press Shift + A > Mesh > Procedural Terrain. A new terrain object will appear with a panel of parameters in the lower-left corner of the 3D Viewport. You can customize:

• Noise Controls: Seed, Zoom, Octaves, Lacunarity, Gain, Amplitude
• Shape & Size: Object Size, Level of Detail, Height, X/Y position
• Triangular Peaks: Three parameters to adjust the sharpness of peaks
• Color Preview: Enable Apply Colors to visualize height zones with flat colors
• Blending Control: Lower Weight, Upper Weight, and Blend define how much low, middle, and high areas dominate

  

  

  

2. Assign Materials (Optional):

After generation, you can assign any number of materials to the terrain manually. Order matters—stack them from highest to lowest terrain zone in the material list.

3. Apply Materials to Terrain:

With the terrain object selected, go to Object > Apply Materials To Terrain. This will combine all assigned materials into one shader based on vertex heights. This feature works with any object, not just terrain!

Tile a texture without repetition (You need to do this manually after applying the materials to terrain):

4. Edit & Export:

You can further sculpt the terrain using Blender’s Sculpting tools. When done, bake the textures and export the asset using Blender’s built-in tools or any export add-ons.

Note: While most PBR or simple textures will blend correctly, some complex materials may not combine properly depending on their node structure.

Installation Instructions:

1. Open Blender and go to Edit > Preferences > Add-ons.
2. Click Install… and select the .zip file of the add-on.
3. Enable the checkbox next to "Procedural Terrain Generator".
4. You're ready to go!
