Creating Realistic 3D Terrains with Blender: Step-by-Step Guide

In this tutorial, we will explore the process of creating realistic 3D terrains in Blender. By following these steps, you will learn how to use various tools and modifiers to achieve a detailed and visually appealing result.

Initial Setup

To begin, let's start by creating a cube and scaling it on the C-axis. Apply the scale by selecting the object and pressing Ctrl + A. Next, add a Subdivision Surface modifier to increase the level of detail.

Modifying the Geometry

  1. Enter edit mode by pressing Tab.
  2. Add a loop cut using Ctrl + R to enhance the geometry.
  3. Duplicate faces by selecting them with A, then pressing Shift + D.
  4. Experiment with duplicating and scaling down the duplicated faces to create interesting variations.

Adding Details

  1. Select a vertex and increase the levels using Ctrl + to refine the shape.
  2. Add a Displace modifier to introduce organic textures. Choose a cloud type, adjust the size and strength for desired effects.
  3. Use different noise textures and settings to customize the displacement.

Working with Materials

  1. In edit mode, select all faces with A, then unwrap them using UV Mapping.
  2. Open the Shader Editor and enable the Node Wrangler addon for more flexibility.
  3. Set up the materials by importing textures and connecting them to the shader nodes.
  4. Adjust the mapping and scale of textures for better results.

Lighting and Rendering

  1. Add a sunlight source to illuminate the scene. Adjust the strength and properties for desired shadow effects.
  2. Utilize a sky texture in the World Properties for realistic lighting.
  3. Experiment with the elevation and rotation settings to enhance the scene.

Creating Grass Textures

  1. Duplicate the shader setup and add a Mix Shader to combine different textures.
  2. Adjust the shader properties and textures to create a realistic grass material.
  3. Use the Color Ramp node to control the distribution of grass textures.

Final Touches

  1. Increase the subdivision levels for smoother surfaces.
  2. Fine-tune the displacement strength for better detail.

Conclusion

By following these steps, you can create captivating 3D terrains in Blender. Experiment with different modifiers, textures, and lighting techniques to enhance your creations. Remember to explore additional resources for more advanced tips and tricks.
