Instant Terrain Importer
Which Blender versions are supported?
Blender 3.6 and newer. Tested on Blender 4.x and 5.x.
Does it work with EEVEE and Cycles?
Yes. Both render engines are supported. Cycles is recommended for best results.
Why is my terrain flat after import?
Increase the Displacement Strength slider in the Modifier Controls section. Default is 50, try higher values for more dramatic terrain.
Why does the terrain look blocky?
Increase the Subdivision slider. Default is 3, try 4–5 for smoother results. Note that higher values require more RAM.
Can I use my own terrain files?
Yes. Add your height and mask files to the Terrains/ folder following the naming format (e.g. XX_height.png, XX_flow.png). You can also point the addon to a custom folder in Preferences
Can I use my own textures?
Yes. Place your texture files in the Terrains/textures/ folder. The addon auto-detects them by suffix (_diff, _nor_gl, _rough, _disp). Select the set from the dropdown and click Apply Textures.
What is the difference between procedural and texture mode?
Procedural mode uses Blender's node-based shader with no external files — works out of the box. Texture mode uses real PBR textures for photorealistic results.
How do I go back to the procedural shader after applying textures?
Click the "Reset to Procedural" button in the Texture Override section.
My normal map looks inverted. What should I do?
Make sure you are using OpenGL (GL) format normal maps, not DirectX (DX). DX normal maps will appear inverted in Blender.
The texture folder is not detected automatically. What should I do?
Make sure your textures are placed inside Terrains/textures/ — the subfolder must be named exactly "textures". You can also set the folder manually in Edit > Preferences > Add-ons > Instant Terrain Importer
Does this work for game engines like Unity or Unreal?
The addon is designed for Blender. You can export the final mesh after applying modifiers, but real-time game engine optimization is not included.
