Creating a Low Poly Terrain in Blender for Unity: A Step-by-Step Tutorial

Are you interested in creating stunning low poly terrains for your Unity projects? In this tutorial, we will guide you through the process of designing a low poly terrain in Blender and seamlessly importing it into Unity for further enhancements. Let's get started!

Setting Up the Scene in Blender

  1. Start a New Blender File:
    • Begin by opening Blender and starting a new file by pressing Ctrl + N.
  2. Creating the Base:
    • Select all items in the scene by pressing A and delete them.
    • Insert a plane by pressing Shift + A under the mesh selection.
    • Scale the plane to your desired size (e.g., 180) by pressing S.
  3. Sculpting the Terrain:
    • Switch to sculpt mode and enable dynamic topology for a more organic look.
    • Use brushes to sculpt the shape of your terrain. Remember, imperfections add to the natural look.
    • Add features like lakes by subtracting height or adding more geometry for variation.

Refining the Low Poly Look

  1. Decimating the Mesh:
    • Switch to object mode and add a decimate modifier to reduce the face count.
    • Adjust the decimate rate to achieve the desired low poly appearance.
  2. Fine-tuning the Details:
    • Use the grab brush to refine specific areas, giving mountains a more distinctive look.

Assigning Colors and Separating Mesh

  1. Dividing the Mesh:
    • Switch to edit mode to separate the mesh into different pieces.
    • Use circle select (C) to choose specific areas and create separate mesh objects (P).
  2. Adding Colors:
    • Define colors for different regions by creating new materials and assigning base colors.

Creating Other Elements and Exporting

  1. Adding Water and Final Touches:
    • Introduce water elements with a translucent appearance for a realistic effect.
  2. Exporting the Terrain:
    • Export your terrain as an FBX file to retain its structure.

Importing into Unity

  1. Setting Up Unity:
    • Open Unity Hub and create a new 3D project.
    • Import the exported FBX file into your Unity project by dragging it into the assets folder.
  2. Finalizing Import:
    • Ensure that colliders are generated for interactions.
    • Drag your mesh into the game hierarchy to import it successfully.
