Procedural Terrain Generator & Material Blending Tool

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.

• 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

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.

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!
